What is the velocity of a ball thrown vertically up?

A ball is thrown vertically up with the velocity of 15 m/s. After two seconds, a stone is thrown upwards with the same speed. What time will the stone meet the ball?

When do two identical balls hit each other 2 seconds apart?

They meet when one ball is going up and other going down, 2 seconds gap means 1 second gap from top point. Originally Answered: Two identical balls are shot upward one after another at an interval of 2 sec. along the same vertical line with same initial velocity of 40 m/s.

How long does it take to solve the ball-to-ball puzzle?

If you understand this properly, it won’t take more than 30 seconds to solve this question. Since they are identical balls on same path, you have to find a position where ball would be on 2 instances 2 second apart. Simply that would be the time where 1 sec before highest position and 1 sec after.

What is the velocity at which the first stone meets the second?

Two stones are thrown vertically upward from the same point with same velocity of 20m/s, at an interval of 2sec after one another.The first stone meet second stone moving upward at 20m/s.What time will the second stone take to meet the first stone? Let t be the time taken by the second stone.

Why does an object thrown upwards come down after reaching a point?

Why an object thrown upwards comes down after reaching a point? When an object is thrown with certain initial velocity (say V), it gains a Kinetic energy at that moment of throwing. As it moves upwards from its initial position (wherefrom it’s thrown) and gains height, its potential energy rises.

Why is the acceleration of the ball negative in the graph?

The acceleration is negative because this acceleration is directing downwards while the ball is moving upward. And because of this negative acceleration, the velocity of the ball is gradually decreasing.
