Question
A ball is thrown upwards, the velocity of the ball when it reaches the maximum height is ___.
- 0
- 9.8
- -9.8
- 10
Hint:
0 m/s
The correct answer is: 0
At the highest point, the object has no kinetic energy where all of its kinetic energy is converted into the potential energy, and therefore, the velocity is zero and the object does not accelerate.
