A solid disk of radius 9.20cm and mass 1.15kg , which is rolling at a speed of 2.30m/s , begins rolling without slipping up a 12.0? slope. How long will it take for the disk to come to a stop?
If the top coil were rotated 90 degrees about a vertical axis through the center of the coil so it is perpendicular to the balance coil, how would the results of the experiment change
A system consists of 4.0 kg of water at 85 degrees Celsius 35 J of work is done on the system by stirring with a paddle wheel, What is the change in internal energy of the system

A 1 115.0 kg car traveling initially with a speed of 25.000 m/s in an easterly direction crashes into the back of a 8 200.0 kg truck moving in the same direction at 20.000 m/s. What is the velocity of the truck right after the collision
A car is traveling at 29m/s when the driver spots a large pothole in the road the distance 37 m ahead. She immediately applies her brakes. If her acceleration is -6.60m/s2, does she manage to stop before reaching pothole.
