A 0.200 kg ball starting from rest rolls down an inclined plane with θ=30°.

a)Find the acceleration of the ball, and the magnitude of normal force exerted by the plane.

b) If it starts from rest a height h = 30.0 cm above its position at the bottom of the incline (measured between the center of the ball at each position), what is the speed of the ball vf at that bottom point, and how long did it take to get there?
