Question

An object is thrown vertically upward with velocity of 20 m/s. At what height will its kinetic energy and potential energy be equal?

Answer 1

Answer:

At 20 metres.

Explanation:

As given:

$\frac{1}{2} m \times {v}^{2} = mgh$

thus, inserting values and cancelling,

$h = \frac{{v}^{2}}{2 \times g}$

thus, neglecting negative value

h~ 20m
