A Block of Mass M = 5

Multiple Choice

A block of mass m = 5.6 kg,moving on a frictionless surface with a velocity of v_i=6.5m/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_f= 0.70m/s. To the left. If the blocks are in contact for 0.20 s,what is the magnitude of the average force on the 5.6-kg block,while the two blocks are in contact?

A) 202 N
B) 192 N
C) 182 N
D) 0.N
E) 0 N
