A Block of Mass M = 5 $v _ { \mathrm { i } } = 6.5 \mathrm {~m} / \mathrm { s }$

question 25

Multiple Choice

A block of mass m = 5.6 kg,moving on a frictionless surface with a velocity of $v _ { \mathrm { i } } = 6.5 \mathrm {~m} / \mathrm { s }$ to the right,collides with a block of mass M at rest,as shown in the figure.After the collision,the 5.6-kg block recoils with a velocity of $v _ { \mathrm { f } } = 0.70 \mathrm {~m} / \mathrm { s }$ to the left.If the blocks are in contact for 0.20 s,what is the magnitude of the average force exerted on the 5.6-kg block,while the two blocks are in contact?
