Suppose you are in an elevator that is moving upward with a constant velocity. a scale inside the elevator shows your weight to be 600 n.
(a) does the scale register a value that is greater than, less than, or equal to 600 n during the time when the elevator slows down as it comes to a stop?
(b) what is the reading when the elevator is stopped?
(c) how does the value registered on the scale compare to 600 n during the time when the elevator picks up speed again on its way back down? give your reasoning

In the sport of parasailing, a person is attached to a rope being pulled by a boat while hanging from a parachute-like sail. a rider is towed at a constant speed by a rope that is at an angle of 15 ∘ from horizontal. the tension in the rope is 1900 n. the force of the sail on the rider is 30∘ from horizontal. what is the weight of the rider? express your answer with the appropriate units.

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
