Question Completion Status: A 65-kg woman in an elevator is accelerating downward at a rate of 1.5 m/s . What is the magnitude of the force exerted by the elevator floor on the woman's feet? QUESTION 7 Two people play tug of war. The 100-kg person on the left pulls with 1200 N, and the 70-kg person on the right pulls with 800 N. Assume that neither person releases their grip on the rope with either hand at any time, assume that the rope is always taut, and assume that the rope does not stretch. What is the magnitude of the tension in the rope in Newtons? QUESTION 8 A man pulls a 4.3-kg sled 47 meters along an angled hill with a force of 32 N, which elevates the man 30 meters above the bottom of the hill. The man then hops on his sled and slides from rest to the bottom of the hill back along his 47 meter path, during which a 304 N frictional force acts upon his sled. How much work in Joules does the man do against friction in pulling the sled up the hill? QUESTION 9 A baseball pitcher throws a 141 g baseball at a velocity of 33 m/s towards home plate. The batter hits the ball, and the velocity of the ball coming off the bat is 54 m/s in the opposite direction of the velocity of the pitch. The bat is in contact with the ball for 0.003 seconds. What is the magnitude in Newtons of the average force applied to the ball
