# A ball is thrown vertically upwards. Its velocity keeps on decreasing. What happens to its kinetic energy when its reaches the maximum height?- Kinetic energy is double
- Kinetic energy is zero
- Kinetic energy is maximum at maximum height
- Kinetic energy is half of initial value

When a is thrown vertically upwards. Its velocity goes on decreasing. And at the peak point, its velocity becomes zero.

And we know kinetic energy $K=\frac{1}{2}mv^2$

Here $m\rightarrow$mass of the body

$v\rightarrow$velocity of the body

If at the peak, its velocity becomes zero. Then, $v=0$

Therefore, $K=\frac{1}{2}m(0)^2=0$

Thus, its kinetic energy becomes zero and gets converted into potential energy when the velocity becomes zero at the maximum point.

Therefore, **b **is correct.
