Impulse: A block of mass m = 5.6 kg, moving on a frictionless surface with a velocity of vi = 6.5 m/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 vf = 0.70 m/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. 34 N
E. 162 N
