The middle pulley is attached to the bottom of the foot, and Problem 4 : The force shown on the figure acts on a 2 50kg object. Problem 5 : An Atwood ma a mass, M, supplies the tension in the ropes. Find the value of the mass. M. The object begins at x = Om with a = Om with a velocity in the positive direction of 1.00meters the masses begin at rest at the same height. After they are released, the large mass, my = 4.10kg. falls Problem 6 : In a physics lab experiment, a compressed spring launches Problem 7 : An archer standing on a 15" slope shoots an arrow 20" above if the force exerted on the bottom of the foot is to be 165N. per second. What is its velocity at x = 4.00m? through a height, h = 1.20m.and the small mass rises, m, - 3.70kg. a distance, h = 1.20m. Assume a 20 g metal ball at a 30 angle. Compressing the spring 20 cm the horizontal (as shown in the figure). How far down the slope that the ropes and pulleys have insignificant mass. What is the velocity of the large mass, after it causes the ball to hit the floor 1.5 m below the point at which it does the arrow hit if it is shot with a speed of 50 meters per second has fallen 1 20m? leaves the spring after traveling 5.0 m horizontally. What is the from 1.75m above the ground? spring constant
