Assignment:
a) As the 35 g is lifted upwards it nudges a 1.3 kg mass at the top of a 1.4 m long frictionless ramp angled at 45 degrees with respect to the floor. The mass slides down the ramp and sticks to a 0/ kg mass resting on a horizontal surface. With what speed (in m/s) do the two blocks begin to move just after the collision?
b) How much energy is lost during the collision in Joules?
c) The coefficient of kinetic friction between the horizontal surface in part b and the joined masses is 0.23. The masses slide for 3 cm before they begin to compress a horizontal spring with a spring constant of 0.4 Nitn. What is the maximum compression of the spring in meters?
d) 1 low much work does friction do on the masses in part d in Joules?
