A car starts from rest and travels for 10.0 s with a uniform acceleration of +2.4 m/s2. The driver then applies the brakes, causing a uniform negative acceleration of -2.0 m/s2. If the brakes are applied for 3.0 s, how fast is the car going at the end of the braking period, and how far has it gone?

A hockey stick of massmsand lengthLis at rest on the ice (which is assumed to be frictionless). A puck with massmphits the stick a distanceDfrom the middle of the stick. Before the collision, the puck was moving with speedv0in a direction perpendicular to the stick, as indicated in the figure. The collision is completely inelastic, and the puck remains attached to the stick after the collision.
