← A ball of mass 200 g moves at 8 m/s towards a bat. The bat pushes it back with a force that changes with time as shown in the graph: it rises steadily to 600 N in 5 ms and falls steadily back to zero in the next 5 ms. The speed of the ball as it leaves the bat isA body is thrown straight up from the surface of the Earth, of radius R, with a speed equal to half the escape speed. Ignoring air resistance, it rises to a height above the surface of →
