Q1. A block of mass 2.7 kg being released from rest on a 1m frictionless plane, inclined at an angle of 40 degree. The block sided down the inclined and struck second block mass of 3.7 kg. If the two blocks stick together, with what speed would they move immediately after the impact?

Q2. A typical Major League fastball is thrown at approximately 96 mph and with a spin rate of 109 rpm. If the distance between the pitcher's point of release and the catcher's glove is exactly 60.05 ft, how numerous full turns does the ball make between release and catch? Neglect any effect of gravity or air resistance on the ball's flight.
