To solve the problem of finding the velocity with which the ball should be thrown up, we can follow these steps: ### Step 1: Understand the motion of the ball When the ball is thrown upwards, it will rise until it reaches a maximum height where its velocity becomes zero. After reaching the maximum height, it will fall back down under the influence of gravity. The distance traveled in the last second of the upward journey is given as 5 meters. ### Step 2: Use the equations of motion We can use the second equation of motion to relate the distance traveled, initial velocity, time, and acceleration due to gravity. The equation is: \[ s = ut + \frac{1}{2} a t^2 \] ...
