A 1.50m long ramp is inclined at 20 degree to the horizontal. A solid ball is released from rest at the top of the ramp.
Part A Find the ball's speed at the bottom of the ramp.
Part B Find its translational acceleration.
For a particular collision you detect the emitted products and find 15 protons, 2 antiprotons, 6 positrons, and 25 neutral particles. How many electrons are also emitted?
