An elevator begins from rest at the first floor of a building. It starts a journey to the fifth floor by moving an acceleration of 1.5 m/s^2 for 3 seconds; thereafter it moves with a constant velocity until it gets near to its stopping point. Then it will stat slowing down at 1 m/s^2 until it reached the 5th floor and stops. Find the apparent weight of a person of mass m who is travelling in the elevator at different times during the motion assuming the person reads 60 kg on a scale.

Draw the position, velocity and acceleration time graph for the ball that hits the wall and then starts rolling down the hill as shown below. Assuming the entire path is frictionless and the ball changed its direction but not the speed as it bounces from the reflecting wall.
