PhysicsEasysingle choice

A body initially at rest is acted upon by a constant force (F) for time (t). The kinetic energy at time $t$ is

Options:

Answer:

Solution:

acceleration $a = \frac{F}{m}$ At time t, velocity $v = at = \frac{Ft}{m}$ Kinetic energy $= \frac{1}{2} mv^{2}$ $= \frac{1}{2} m \frac{F ^{2} t ^{2}}{m ^{2}} = \frac{1}{2} \frac{F ^{2} t ^{2}}{m}$
