What if the boy and the girl pull the heavy crate at the same time? Originally Answered: A boy and a girl are pulling a heavy crate at the same time with 10 units of force each. If they’re pulling in the same direction, then the net force is 20 units. If they’re pulling in […]
How do you calculate retarding force?
How do you calculate retarding force? 1. Find the accelerating and retarding (stopping) force: Accelerating force: First, find acceleration: 50 km/h is equal to 13.89 m/s (we calculated this with the speed converter). Retarding force: a = (0 – 13.89 m/s) / 8 s = -1.74 m/s2 Fr = 50 kg * -1.74 m/s2 = […]
Do airbags actually save lives?
Do airbags actually save lives? NHTSA estimates that the combination of an air bag plus a seat belt reduces the risk of death in frontal crashes by 61 percent. From 1987-2015, frontal air bags saved 44,869 lives. In 2016, air bags are estimated to have saved 2,756 people. Should airbags be on or off? You […]
What is the temperature difference between steam and boiling water?
What is the difference between being charged and being indicted?
What is the difference between being charged and being indicted? A charge is brought against someone by a prosecutor. But in an indictment, a grand jury brings the charges against the defendant. All indictments are charges, but not all charges are indictments. How do you know if you’re being indicted? Basically, if federal agents came […]
How do you solve a spring pulley problem?
How do you solve a spring pulley problem? Hint: To solve this type of problems, the first step is to find the mean position of the spring mass system i.e. the natural length of the spring is the position of equilibrium point. Second step is to displace the object from its mean position, the restoring […]
Which of the following is evidence of plate tectonics?
Which of the following is evidence of plate tectonics? Material in the mantle is constantly circulating as a result of heat within the mantle. As the partially molten rock flows, the tectonic plates move as well. Other evidence of plate tectonics include Seafloor spreading, which involves the creation of new crust at divergent plate boundaries. […]

What is the maximum acceleration of a bungee jumper?
What is the maximum acceleration of a bungee jumper? We can see this because the upward force is at a maximum when the bungee cord is fully stretched. The jumper reached the highest position in the middle of the second free-fall period, or about 2.4 s. The acceleration is downward and about –9.8 m/s2. How […]
Do wider tires affect gas mileage?
Do wider tires affect gas mileage? For example, larger tires decrease your fuel economy because they are heavier, while smaller tires increase fuel efficiency. Bigger tires also have a higher rolling resistance than smaller tires which means they require more resistance and effort to get them rolling. What are good tires for rain? The 10 […]
