Question: A ball with a radius of r = 1.96 cm and a mass of m = 18.6 g is released from rest at the top of a track (Figure 1). The ball starts from a height of h = 1.332 m and, after rolling down a straight section, it rolls around a curved section of radius R = 0.282 m. ? -.> h R Figure 1: Diagrammatic representation of a ball of radius r positioned at the top of a straight slope of height h (n.b. the straight section is of height h) that descends from left to right. At the bottom of the straight section, the slope becomes curved and loops around itself in the form of a three Figure 1: Diagrammatic representation of a ball of radius r positioned at ti quarter-circle of radius R.

The horizontal unit vecto on and the vertical unit vector j is positive in an upwards direction. Diagram is not to scale.Part 1) At the moment it is released how much energy does the ball have? Assume that the ball has 0 potential energy at its lowest position on the track. E; = Part 2) How much rotational kinetic energy does the ball have at its lowest point on the track? Krot = Part 3) What is the speed of the ball at the top of the circular loop? U = m/s
