QUESTION 4A block of mass 1.99 kg is placed on a frictionless floor and initially pushed northward, whereupon it begins sliding with a constant speed of 3.88 m/s. It eventually collides with a second, stationary block, of mass 3.90 kg, head-on, and rebounds back to the south. The collision is 100% elastic. What will be the speeds of the 1.99-kg and 3.90-kg blocks, respectively, after this collision? 2.64 m/s and 1.94 m/s 0.63 m/s and 1.60 m/s 1.26 m/s and 2.62 m/s 2.62 m/s and 1.26 m/s

QUESTION 4

A block of mass 1.99 kg is placed on a frictionless floor and initially pushed northward, whereupon it begins sliding with a constant speed of 3.88 m/s. It eventually collides with a second, stationary block, of mass 3.90 kg, head-on, and rebounds back to the south. The collision is 100% elastic. What will be the speeds of the 1.99-kg and 3.90-kg blocks, respectively, after this collision?

2.64 m/s and 1.94 m/s

0.63 m/s and 1.60 m/s

1.26 m/s and 2.62 m/s

2.62 m/s and 1.26 m/s
