Which hits the ground first if they start at the same height a dropped ball or a ball launched with Ahorizontal velocity?
As gravity is the only force in both cases, both balls will hit the ground at the same time. When you throw a ball, we are assuming that you are throwing it horizontally. This means you are giving the ball only horizontal velocity.
When two particles each of mass m are dropped from a height H and 2h respectively the ratio of their times to reach the ground is?
Two balls are dropped from heights h and 2h respectively from the earth surface. The ratio of time of these balls to reach the earth is. t=√2hg⇒t1t2=√h1h2=√12=1√2.
Will both the balls reach the surface at same time or different time?
This approximation is pretty good if we are only interested in exploring distances much smaller than Earth’s radius. In this approximation, the two balls will always hit the ground at the same time, no matter what speed they leave the surface with.
How far below the top of the tower do the balls meet?
The balls meet 78.4 meters below the top of the tower. Q: A ball is dropped from the top of a tower with a height of 100m and at the same time, another ball is projected vertically upwards from the ground with a velocity of 25m/s. What is the distance from the top of the tower at which the two balls meet?
What is the velocity of the ball dropped from the tower?
From the top of a tower 100m in height a ball is dropped and at the same time another ball is projected vertically upwards from the ground with velocity of 25ms −1. Find when and where the two balls will meet.
What happens when a ball is dropped from a 100m high?
physics A ball is dropped from the top of a building 100 m high. At the same instant another ball is thrown upwards with a velocity of 40 ms−1 from the bottom of the building. The two balls will meet after.
What happens from the top of a tower 100m in height?
>> From the top of a tower 100… From the top of a tower 100m in height a ball is dropped and at the same time another ball is projected vertically upwards from the ground with velocity of 25ms −1. Find when and where the two balls will meet.
