What is the mass of an object that requires a force of 30 N to accelerate at a rate of 5 m s2?

What is the mass of an object that requires a force of 30 N to accelerate at a rate of 5 m s2?

6 kg

What is the mass of an object if a force of 17 N causes it to accelerate at 1.5 m s2?

Answer. m= 11.4g.

What is the mass of an object that needs a force of 4500 N to accelerate it at a rate of 5 m s2?

1 Answer. The mass of the object is 900 kg.

What is the mass of an object that needs a force of 4 500 N to accelerate it at a rate of 5m sec 2?

Answer. so, 900 is the mass of that body.

How much force is the wall exerting on the rope?

Note that by Newton’s Third Law, the force exerted by a wall on a rope is the same as the force exerted by the rope on the wall.

How do u calculate force?

What is the formula for force? The force formula is defined by Newton’s second law of motion: Force exerted by an object equals mass times acceleration of that object: F = m ⨉ a. To use this formula, you need to use SI units: Newtons for force, kilograms for mass, and meters per second squared for acceleration.

What force is required to accelerate a body?

Answer Expert Verified The equation for force is force is equal to mass times acceleration or F = ma where Force or F is measured in Newtons or N (which is also kilogram-meter per second squared), Mass or m is measured in kilograms or kg, and acceleration is measured in meters per second or m/s2.

What is the formula for calculating speed?

The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time.

How can I calculate average?

The average of a set of numbers is simply the sum of the numbers divided by the total number of values in the set. For example, suppose we want the average of 24 , 55 , 17 , 87 and 100 . Simply find the sum of the numbers: 24 + 55 + 17 + 87 + 100 = 283 and divide by 5 to get 56.6 .

What is the formula to calculate average percentage?

Calculate the percentage average To find the average percentage of the two percentages in this example, you need to first divide the sum of the two percentage numbers by the sum of the two sample sizes. So, 95 divided by 350 equals 0.27. You then multiply this decimal by 100 to get the average percentage.

How do I calculate percentage of a total?

To find the percentage of the marks, divide the marks obtained in the examination with the maximum marks and multiply the result with 100. Example 1: If 1156 is the total score obtained in the examination out of 1200 marks, then divide 1156 by 1200, and then multiply it by 100.

What is average in math?

In maths, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.

Why do we calculate average?

The average is the value that can replace every existing item, and have the same result. If I could throw away my data and replace it with one “average” value, what would it be? One goal of the average is to understand a data set by getting a “representative” sample.

How do I calculate mean?

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

How do you work out mean median and mode?

To find the mode, order the numbers lowest to highest and see which number appears the most often….The median is the middle value.

1. To find the median, order the numbers and see which one is in the middle of the list.
2. Eg 3, 3, 6, 13, 100 = 6.
3. The median is 6.

What is the formula for median of grouped data?

The formula for median in a grouped data is median=l+(n2−cff)×h, where l represent the lower limit of the median class, n represents the total sum of all frequencies, cf represent the cumulative frequency before the median class, f represent the frequency of the median class and h represents the class width.

What is the math mode?

more The number which appears most often in a set of numbers. Example: in {6, 3, 9, 6, 6, 5, 9, 3} the Mode is 6 (it occurs most often).

What if there is no mode?

It is possible for a set of data values to have more than one mode. If there are two data values that occur most frequently, we say that the set of data values is bimodal. If there is no data value or data values that occur most frequently, we say that the set of data values has no mode.

What happens when you have 2 modes?

A set of numbers can have more than one mode (this is known as bimodal if there are two modes) if there are multiple numbers that occur with equal frequency, and more times than the others in the set.

What is mode math example?

Mode: The most frequent number—that is, the number that occurs the highest number of times. Example: The mode of {4 , 2, 4, 3, 2, 2} is 2 because it occurs three times, which is more than any other number. Want to learn more about mean, median, and mode?
