A body projected vertically from the earth reaches a height equal to earth’s radius before returning to the earth. The power exerted by the gravitational force is greatest : |
At the instant just after the body is projected At the highest position of the body At the instant just before the body hits the earth It remains constant all through |
At the instant just before the body hits the earth |
P = \(\vec{Fv} = Fv Cos \theta\) Just before hitting Ө is zero and both F, v are maximum. |
