Problem 8 : A small sphere of radius r0 = 1.5 cm rolls without slipping on the track shown in the figure whose radius is R0 = 25.0 cm . The sphere starts rolling at a height R0 above the bottom of the track. (Figure 1) Part A When it leaves the track after passing through an angle of 135 ∘as shown, what will be its speed? Express your answer using two significant figures. Part B When it leaves the track after passing through an angle of 135 ∘ as shown, at what distance D from the base of the track will the sphere hit the ground? Express your answer using two significant figures.
