A body is initially moving with a velocity of 5 m/s. It undergoes an acceleration of 2 m/s2 for 4 seconds. Find the displacement (in m) of this body in these 4 seconds.
A body moving in a circular path with a constant speed has a
A body of mass 5 kg accelerates from 12 m/s to 20 m/s in 4 seconds due to the application of a force on it. Calculate the magnitude of this force (in N).
A body that is moving with uniform acceleration covers 200 m in the first 2 s and 220 m in the next 4 s. The velocity in m/s after 7 s is
