What is the final velocity when a body is dropped from a height?
Answer: final velocity of the object will be 0 m/s.
What is the initial velocity when a body is dropped from a height?
Initial velocity of a body when dropped from a height is zero, i.e., u=0.
When an object is dropped the initial velocity is zero?
If the object is dropped, we know the initial velocity is zero. Once the object has left contact with whatever held or threw it, the object is in free-fall. Under these circumstances, the motion is one-dimensional and has constant acceleration of magnitude g.
When a body is dropped or thrown horizontally?
Assertion: When the body is dropped or thrown horizontally form the same height, it would reach the ground at the same time. Reason: Horizontal velocity has no effect on the vertical direction. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.
What is the velocity when it reaches the ground?
the speed of the object when hits the ground is the velocity at time t∗, where t∗ is the value of t when s(t)=sG=0 (if your reference system is placed at s=sG=0 for the ground).
How do you find final velocity before hitting the ground?
Choose how long the object is falling. In this example, we will use the time of 8 seconds. Calculate the final free fall speed (just before hitting the ground) with the formula v = v₀ + gt = 0 + 9.80665 * 8 = 78.45 m/s .
How much time in seconds does the ball spend in the air before it reaches the ground?
1 Expert Answer The ball hits the ground after 4 seconds.
How long will a ball stay in the air?
If you throw a ball straight up in the air how long does it stop for before starting to go down? It stops, for zero amount of time, right at the peak of its travel. It does not remain at that peak for any length of time. It stops, for zero amount of time, right at the peak of its travel.
How long will a projectile stay in the air?
The time for projectile motion is completely determined by the vertical motion. So any projectile that has an initial vertical velocity of 14.3 m/s and lands 20.0 m below its starting altitude will spend 3.96 s in the air.
Why does mass not affect projectile motion?
When an object is dropped from a tower, mass does not affect final velocity or time. When writing equations of motion for a dropped object, mass is in the equations in 2 places and they cancel out. That is basically the reason that mass does not affect the results of analysis of a projectile.
