You throw a bowling ball of mass M and radius 1m has an initial speed v0 down the lane. It has an initial angular velocity of 3v0/R just after its release. The coefficient of kinetic friction is 0.08. It begins to roll without slipping at t=2s. What is the speed of the ball just as it begins rolling without slipping?

The speed of light in a material is 0.50 c. what is the critical angle of a light ray at the interface between the material and a vacuum?

Scout feels ill one day before school. her mother puts a thermometer in her mouth and the temperature begins to climb to 100°f. what is happening between the cooler thermometer and scout's body? a) scout's body is applying a force to the particles in the thermometer. b) kinetic energy is being transferred from her mouth to the thermometer. c) potential energy is being lost by the thermometer and gained by scout's body. d) the potential energy stored in foods is converted to mechanical energy to raise the mercury in the thermometer.
