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 $v _ { f } = 0.70 \mathrm {~m} / \mathrm { s }$
the magnitude of the average force on the 5.6-kg block, while the two blocks are in contact?

• A) 182 N
• B) 0 N
• C) 1 N
• D) 202 N
• E) 192 N
