Question

a body of mass M accelerates uniformly from rest to a speed v in t second. the average power delivered is?​

Answer 1

Explanation:

we can find the acceleration produced by the mass given by

$a = \frac{v}{t}$

hence the Instantaneous value of power would be given by

$dp = \frac{mv}{t} \times v = \frac{m {v}^{2} }{t}$

so the answer is

$\frac{m {v}^{2} }{t}$
