Question

1. A spring of negligle 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 less than that of M2. Input whether the following statements are greater than, less than, or equal to one another.

a) The duration of the force exerted by spring on M1 is..... the time the force acts on M2

b) The force exerted by the spring on M1 is .... the force it exerts on M2

c) The kinetic energy of M2 is ..... the kinetic energy of M1 once they both lose contact with the spring.

d) The speed of M2 is .... the speed of M1 once they both lose contact with the spring.

e) The momentum of M1 is .... the momentum of M2 once they both lose contact with the spring.

f) The final height up the ramp reached by M1 is .... the height reached by M2.
