A receiver is in a jet flying alongside another jet that is emitting 2.0 x 106 Hz radio waves. If the jets fly at 268 m/s, what is the change in frequency detected at the receiver?

g The ball has a mass of 150 grams. If the ball has a positive charge, what initial velocity must it have at the 200-V level for it to reach its maximum height at the 700-V level

For the following question neglect air resistance. Pay particular attention to whether the answer involves "absolute" quantities that have only magnitude (e. g., speed) or quantities that can have either sign (e. g., velocity).

A person with a weight of 956 N runs up a 2.41 m staircase. If it takes 4.17 seconds to reach the top, how much power was generated?

A particle moves along the x axis. It is initially at the position 0.270 m, moving with velocity 0.140 m/s and acceleration 20.320 m/s2. Suppose it moves as a particle under constant acceleration for 4.50 s.
