3. You step into an elevator on the 44th floor of a tall office building. Each floor is 3.50 m above the one below it You're alone in the elevator. You select your destination floor , then-as you wait for the door to close-you notice: There is a bathroom scale with a mass of 2.43 kg resting on the elevator floor. (Naturally-why wouldn't there be?) You decide to stand on the scales during the ride. (Naturally-why wouldn't you?) Weight (N)...

KINEMATICS AND KINETICS OF A PARTICLE Problem 1 (15 Pts.) The 2.3 Mg (Mega grams) mine car is being pulled by the winch M mounted on the car. If the winch exerts a force of F (367t2) Newton on the cable, where t is in seconds, determine the power output of the winch when t - 12 s, starting from rest. The crate, which has a mass of 232 kg, is subjected...
