Kinematics of motion in a straight line — practice question
A particle is let go from rest at a point $H$ m above the horizontal ground and travels straight downwards. It goes past a point $35$ m above the ground at a speed of $(V - 10)$ m s$^{-1}$ and then hits the ground at speed $V$ m s$^{-1}$. Find
