Question
1) Two blocks of masses m and M [M=2.69 m] are placed on ahorizontal, frictionless surface. A light spring is attached to oneof them, and the blocks are pushed together with the spring betweenthem. A cord holding them together is burned, after which the blockof mass M moes to the right with a speed of 2.06 m/s. What is thespeed of the block of mass m? Answer in units of m/s. 2) A(n) 88 g particle moving with an initial speed of 150 m/sin the positive x direction strikes and sticks to a(n) 180g particle moving with 62 m/s in the positive direction. How much kinetic energy is lost in this collision?Answer in units of J. 1) Two blocks of masses m and M [M=2.69 m] are placed on ahorizontal, frictionless surface.

How much kinetic energy is lost in this collision?Answer in units of J.Explanation / Answer
=1107.21654 - 1335.96 =-228.74346 JYou are asked to find the how much kinetic energy islost, so the answer is 228.7 J (no negativesign)
