Power

Question

A body is initially at rest. It undergoes one dimensional motion with constant acceleration. The power delivered to it in time t is proportional to

Moderate

A

$t^{\frac{1}{2}}$
B

t
C

$t^{\frac{3}{2}}$
D

$t^{2}$

Solution

$i f f o r c e i s c o n s \tan t m \frac{d v}{d t} = k (c o n s \tan t) o n i n t r e g a t i o n m v = k t v \infty t p o w e r = F x v = F x \frac{k t}{m} p o w e r \infty t$
