A75.0-kg painter climbs a ladder that is 2.75 m long leaning against a vertical wall. the ladder makes a 30.0° angle with the wall. (a) how much work does is done by gravity on the painter? (b) does the answer to part (a) depend on whether the painter climbs at constant speed or accelerates up the ladder?

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
