please answer this and show your solutions. I will give you a very good feedback! Thank you in advance.

1. A ball bearing of mass 0.2kg is released from rest at point A. It follows a curved (1/4 of a circle) path as shown in fig. 1 which has a radius r = 0.5m. When the ball leave the track at point B, it will proceed to fall down to the floor in a projectile motion. The height of point B from the floor is 1.2m. A) What are the velocities of the ball when it is at point A? Point B? and point D? Show your solution and explain how you got your results. Tabulate your results in table 1. B) Calculate the kinetic energies, the potential energies and total energies at level A, B, and D. Again, show your solutions and tabulate your results in table 1. C) From the data of table 1, calculate the horizontal distance R. B hi =1.2m Q C R fig. 1 Table 1.
