Determine the velocity with which he must throw the ball so that the ball enters the basket.

A car starting from rest accelerates uniformly at the rate of ?? to reach a maximum speed of ??. It then travels at this speed for some time and decelerates uniformly at the rate of ?? to come to rest. Given the total distance travelled by this car is ??, determine the total time taken. Q2. (10 marks) A basketball player who is 2 m tall jumps 0.25 m above the ground and shoots the ball into the basket from a point that is 4 m from the basket as shown below. Determine the velocity with which he must throw the ball so that the ball enters the basket.
