Q- An aluminum block is pushed to the right with and initial speed of v₁=10 ft/s at the same time a copper block is pushed to the left with an initial speed of v₂=16 ft/s. both blocks slide along a horizontal steel floor toward each other. if the blocks were initially d = 10 ft. apart determine how far each block slides before they collide. the kinetic friction for the aluminum block = 0.47 and the kinetic friction for the copper block = 0.36.

Solution:
