- A mass M1 (of 2.5 kg) slides without friction on a table at a speed of 5 m/sec towards a mass M2 of 5 kg which can also slide without friction on the table. There is a spring on the face of M2 that will contact M1. If the spring constant is 100 N/m, what will be the maximum compression of the spring?10. Block 1 with a mass of 1.0 kg slides down a frictionless ramp with a height of 3.0 m and collides with block 2 which has a mass of 2.0 kg.

At an ice skating rink they stand close together on skates, at rest and facing each other, with a compressed spring between them. The spring is kept from pushing them apart because they are holding each other. When they release their arms, Al moves off in one direction at a speed of 0.90 m/s, while Jo moves off in the opposite direction at a speed of 1.2 m/s. Assuming that friction is negligible, find Al's mass.
- 3. John is performing an experiment in a Uwindsor lab. In this lab, John has two toy car's of mass m1 and m2 connected together to form a car of mass m whose velocity is v. While traveling a force causes these car's to separate, with the heavier car being at rest as a result. If John notes the kinetic energy of the moving car is 28 mv 2 what is the mass of the moving car?

The mass of the snowball, in grams, is what?Bryce, a mouse lover, keeps his four pet mice in a roomy cage, where they spend much of their spare time, when they're not sleeping or eating, joyfully scampering about on the cage's floor. Bryce tracks his mice's health diligently and just now recorded their masses as 0.0109 kg, 0.0175 kg, 0.0137 kg, and 0.0189 kg.
