Amotorcycle passes over the top of a hill that has a radius of 100m. the mass of the motorcycle rider is 300kg. the motorcycle is moving at a speed of 30m/s. the surface exerts a normal force of magnitude fn on the motorcycle. the motorcycle passes over the top of the hill again but now is moving at a speed of 33m/s. how does the new normal force exerted on the motorcycle compare to fn?

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
