A spring of negligible mass is compressed between two masses on a frictionless t

Question

A spring of negligible mass is compressed between two masses on a frictionless table with sloping ramps at each end. (Note: the masses are not attached to the spring in any way, and so will fly apart after release.) 15.11pt] The masses are released simultancously. The mass MI is greater than that of M2. Select the appropriate symbol for each statement: G (Greater than), L (Less than), or E (Equal to). (If the first two are 'greater than, and the last four 'less than,' then enter GGLLLL). M1 M2 A) The final height up the ramp reached by MI is... the height reached by M2 B) The kinetic energy of M1 is... the kinetic energy of M2 once they both lose contact with the spring. C) The magnitude of the force exerted by the spring on M1 is that it exerts on M2. D) The magnitude of M2's momentum is.. that of MI before and just after loss of contact with the spring. E) The duration of the force exerted by the spring on M1 is the time the force acts on M2. D The speed of M2 is the speed of MI once they both lose contact with the spring.

Explanation / Answer

A) M1> M2 => v1<v2 => h1<h2

B) M1>M2, P1 = P2 => K = P2/2M => K1<K2

C) Equal

D) Equal

E) Equal

F) Greater

=> LLEEEG
