Question Solved1 Answer Problem 1. A heavy particle M moves up a rough surface of inclination a = 30 to the horizontal. Initially the velocity of the particle is v, = 15 m/s. The coefficient of friction is f = 0.1. Determine the distance travelled by the particle before it comes to rest and the time taken. Problem 1.
