Starting from rest, a child throws a ball of mass m with an initial speed v, at an angle B with the horizontal direction. The child
then chases after the ball, accelerating at a constant acceleration a . If the child wants to catch the ball at the same height as it
was thrown, what must be the child's acceleration a ? Express your answer in terms of some or all of the variables v, m, B and
g for the gravitational constant. Express the trigonometric functions in terms of the basic sin(B), cos(B) or tan(B).

Case 1: A DJ starts up her phonograph player. The turntable accelerates uniformly from rest, and takes t1 = 10.7 seconds to get up to its full speed of f1 = 78 revolutions per minute.Case 2: The DJ then changes the speed of the turntable from f1 = 78 to f2 = 120 revolutions per minute. She notices that the turntable rotates exactly n2= 16 times while accelerating uniformly.

The bullet had entered the barrel with a speed 310 m/s traveling horizontally and the pistol was held at a height of 1.5 m.
