Question

An object is thrown vertically upwards with velocity of 20m/s. At what height will its kinetic energy and potential energy be equal ? (g = 10 m/s⁻²)
(A) 10 m
(B) 20 m
(C) 15 m
(D) 5m

Answer 1

K.E and P.E will be equal at 20 m.

On substituting values in the below equation we get h=20 m(B)

1/2 m v^2 = m g h

Answer 2

Answer:

the two values are equal.by substituting g=10 m/s-2 . it would be 20 m
