Question
() THE FOLLOWING QUESTIONS ARE BASED ON THE INFORMATION GIVEN BELOW.
Block m, of mass 15 kg moving with velocity v = 33 m/s on a frictionless plane collides block mg which is connected to block
m3 by a long. massless spring with spring constant k = 7000 N/m: see the figure. Each of blocks mą and mg has a mass of 5 kg.
Before the collision, blocks mą and mg are stationary and the spring is relaxed.
m2
Frictionless -
For parts A. B and Cassume that the collision of blocks m, and ma is completely inelastic. (Because the spring is relaxed
before the collision. block mạ does not move at the instant of impact therefore (m, +m2) must move through a finite
displacement before any force acts on mg and cause it to move)
• For parts D and Eassume that the collision of blocks m, and m, is elastic. (Because the spring is relaxed before the
collision. block my does not move at the instant of impact therefore mạ must move through a finite displacement before any
force acts on mg and cause it to move)
D) After the collision, what is the speed of block m, in units of meters per second?
