A 30 kg block that has Velatoontis sides slides across a level surface of slick ice and hits a 20
kg block that is initially at rest and has sticky Velcro on its surface. The blocks stick together and move
off in the same direction the 3.0 kg block was moving. Their speed after the collision is 10.0 m/s. How
fast was the 3.0 kg block moving before the collision?
