O/6 points The figure below shows an arrangement with an air track, in which a cart is connected by a cord to a hanging block. The cart has mass m10.680 kg and its center is initially at xy coordinates (-0.500 m, 0 m). The block has mass m20.260 kg and its center is initially at xy coordinates (O, -0.100 m). The mass of the cord and pulley are negligible. The cart is released from rest, and both cart and block...
Problem 2: (6 pts)) Two masses are connected by a string as shown in the figure below. Mass mp 2.00 kg moves up while ma 12.0 kg moves down a frictionless inclined. The pulley is frictionless and has a mass M 2.00 kg, and a radius R 0.200 m (1- MR?) (a) Draw the free body diagram for the masses and pulley separately (b) Use Newton's Second Law of Motion to find the resulting acceleration 2pts) of both masses. (c)...
I need the answer for QUESTION 4 not 3.
4. Consider your answer to the previous problem (part a). Assume m1 = 4.00 kg, m2 = 2.00 kg and the pulley has a radius of R = 6.00 cm and a mass M = 3.00 kg. The magnitude of the frictional torque exerted on the pulley is 0.500 N.m. (a) Starting from rest, how long does it take for the 4.00 kg block to reach the floor, which is 1.0...
1. KINEMATICS: Kickoff During kickoff for the Oakland Raiders, Sebastian Janikowski's powerful left leg launches the ball from the 30-yard line with the initial velocity of 30 m/s. a. Assuming no air resistance, can the ball reach the end of the field, i.e. travel at least 80 yards (73 m), resulting in a touch-back? Please explain (a yes or no answer is not sufficient) b. Assuming Mr. Janikowski chose the best possible angle for the kick, how long is the...
