A ball is thrown upwards and caught when it comes back down. In the absence of air resistance, the speed of the ball when caught would be Group of answer choices
more than the speed it had when thrown upwards.
less than the speed it had when thrown upwards.
the same as the speed it had when thrown upwards.
none of the above
In the absence of air resistance, the speed of the ball when it is caught will be the same as the speed it had when thrown upwards. This is due to the principle of conservation of energy and the symmetry of projectile motion. When the ball is thrown upwards, it slows down due to gravity until it reaches its highest point, and then it accelerates back down to the original height, regaining the same speed it had when it was thrown.
Therefore, the correct answer is:
**the same as the speed it had when thrown upwards
