Vedclass · Answer

(B) Let the mass of the body be $m$ and the constant acceleration be $a$.According to Newton's second law of motion,the force $F$ acting on the body is:$F = ma$Since $m$ and $a$ are constants,the force $F$ is also constant.For a body starting from rest $(u = 0)$,the velocity $v$ at time $t$ is given by the equation of motion:$v = u + at = 0 + at = at$Thus,$v \propto t$.Power $P$ delivered to the body is defined as the product of force and velocity:$P = F \cdot v$Substituting the expressions for $F$ and $v$:$P = (ma) \cdot (at) = (ma^2)t$Since $m$ and $a$ are constants,$ma^2$ is also a constant.Therefore,$P \propto t$.

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