A spring of negligible mass is compressed between two masses on a frictionless table with sloping ramps at each end. The masses are released simultaneously. The masses have the same volume, but the density of M1 is greater than that of M2. Select the appropriate option for each statement.
A) The magnitude of the force exerted by the spring on M2 is ... that it exerts on M1.
B) The final height up the ramp reached by M1 is ... the height reached by M2.
C) The speed of M1 is ... the speed of M2 once they both lose contact with the spring.
D) The magnitude of M1's momentum is ... that of M2 before and just after loss of contact with the spring.
E) The kinetic energy of M1 is ... the kinetic energy of M2 once they both lose contact with the spring.
F) The duration of the force exerted by the spring on M1 is ... the time the force acts on M2.
