How high most a body be lifted to gain an amount of P.E. equal to K.E. is when moving at speed 20ms^(-1).(The value of acceleration des to grity at a place is (9.83ms^(-2))

How high most a body be lifted to gain an amount of P.E. equal to K.E.

1.	How high most a body be lifted to gain an amount of P.E. equal to K.E. is when moving at speed 20ms^(-1).(The value of acceleration des to grity at a place is (9.83ms^(-2))
Answer» ANSWER :`mgh=1/2mv^(2)` so h=20.2m
