Thanks dude

Answer 1

A cylinder rolls in a horizontal plane having centre velocity 25 m/s.
At its age the velocity is due to its rotation as well as due to its leniar motion & this two velocities are same and acts in the same direction (v = r ω)
Therefore Net velocity at A = 25 m/s + 25 m/s = 50 m/s
