The momentum increases linearly as speed increases, that is, doubling the speed doubles the momentum, tripling the speed triples the momentum. What happened to the kinetic energy when the speed was doubled and tripled

The motor m applies a time-varying force of f (200 t) n, where t is in seconds. box b with mass 200 kg starts from rest, and the coefficients of kinetic and static friction are 0.2 and us 0.3 the acceleration due to gravity is g 9.8 m/s2 b 300 a) find the time ' when the box starts to move. b) calculate the speed of the crate at 3 s c) calculate the power delivered by the motor at t 3 s

Explain earth's motion, using the terms "precession" and "rotation" in your answer.

Apropagating wave in space with electric and magnetic components. these components oscillate at right angles to each other. it may travel in a vacuum.
