Bob (m = 60kg) is wearing a sticky suit. Just as he reaches his desired speed of 6m/s, he reaches the edge of ice (assume the ice is frictionless) and collides with a large crate (m = 250kg). Bob and the crate stick together and slide along level ground (uk = 0.60). a) How far do Bob and the large crate slide before coming to rest? b) How elastic was the collision? c) How much thermal energy has been generated during the slide?
If the electric field is zero in some region of space, the electric potential must also be zero in that region. The value of the electric potential can be chosen to be zero at any convenient point. In electrostatics, the surface of a conductor is an ..
Consider a container with a partition in the middle. The container is thermally isolated from the environment. Initially one half of the container is filled with gas A (N molecules) and the other half with gas B (also N molecules).
Elm Street has a pronounced dip at the bottom of a steep hill before going back uphill on the other side. Sitting on the scale while the car is parked gives a reading of 588 N. Analyze your data, using a graph, to determine the dip's radius of curv..
At a time t = 3.40s , a point on the rim of a wheel with a radius of 0.210m has a tangential speed of 53.0m/s as the wheel slows down with a tangential acceleration of constant magnitude 11.0m/s2. Calculate the wheel's constant angular accelerat..
