2m/s. 3 M/ mi= 2kx ma = 5kg after collision, bounce back, with speed Im/s. Q , what is the final speed of Mz ? Q 2 What is the change in KE of the entire system ? if M. & my Stick together. W What is the change in KE of the entire system?Isping not attached to MZ 2 mz no friction, surface. mi & mz both @ rest, spring Compressed by 2 cm, K = 50 N/m, after the spring is released, Q 1 what Is final velocity of m, and mz ) Q2 , What is the change in KE of the system1 = 2m . M2 hof on all surface. MI = 2kg. mz= 1kg initially both @ rest after they Seperate, What is Up for m. and my what is the AKE of whole system
