Question

a) A tennis player hits a volley just above ground level, in a direction perpendicular to the net. The ball leaves her racquet at 11.8 ms-1 at an angle of

25° to the horizontal. If you assume that there were no spin, air resistance and initial height is 0. Will the ball clear the net if it is 2.8 m away and 95 cm high at this point? O In the following question take the acceleration due to gravity as 9.81 m s-2and assume air resistance is negligible. A Lancaster bomber drops a 'bouncing bomb' at a horizontal speed of 85.0 ms-1 and at a height of 45.0 m above the water in a reservoir. Calculate i)The time it takes the bomb to hit the water surface The horizontal distance it moves after being released to the point where it first touches the water
