A 94 kg physics student is wearing a 3 kg jacket. He is stranded in the middle of a frictionless frozen pond. Since there is no friction, he cannot walk off the pond since his shoes can't grip the ice. Since he cannot escape the ice, surely he is doomed to freeze to death. Luckily, since the student is in physics class, he knows conservation of momentum. He takes off his jacket and throws it east with a velocity of 15 m/s.

What is the magnitude of the student's velocity after throwing the jacket?

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.

The slope of a velocity time graph over any interval of time gives the during that interval

Which notation is used to represent an alpha particle? a. b. c. d.
