Unformatted text preview: determine the magnitude of the acceleration of a train engine moving with a constant speed of 12 m/s when it is at point x = 180 m. Question 3:- The ball has a mass m and is attached to the cord of length l. The cord is tied at the top to a swivel and the ball is given a velocity v0. Show that the angle which the cord makes with the vertical as the ball travels around the circular path must satisfy the equation tan sin = v0 /gl. Neglect air resistance and the size of the ball....
