1.	A body is initially at rest. It undergoes one dimensional motion with constant acceleration. The power delivered to it at time t is proportional to
Answer» <P>`t^(1//2)` `t` `t^(3//2)` `t^2` Solution :Using `V = u + at :.v = at ( :. u = 0)` As power , `P = F xx v :. P = (ma) xx at = ma^2 t` As m and a are CONSTANTS, `:.` P prop t` .
