Applications of Newton's Laws 1. A sports car of mass 1000 kg can accelerate uniformly from rest to 27 m/s in 7.0 5. What is the forward force on the car? 2. Three connected blocks are pulled to the right on a horizontal frictionless table by a force of magnitude T3 = 65.0 N . If m1 = 12.0 kg, m2 = 24.0 kg , and m3 = 31.0 kg , calculate (a) the magnitude of the system's acceleration, (b) the tension '17] , and (c) the tension T2 . A block of mass m1 = 3.70 kg is held on a frictionless plane inclined at angle 9 = 30.0 is connected by a cord over a massless, frictionless pulley to a second block of mass m2 = 2.30 kg as shown in the gure. It is then released and moving up the incline. (a) Draw the FBD and KD of m] and m2 (b) Find the magnitude and direction of the acceleration of each block (0) Find the tension in the cord. An object is hung from a spring balance attached to the ceiling of an elevator cab. The balance reads 65 N when the cab is standing still. What is the reading when the cab is moving upward (a) with a constant speed of 7.6 m/s and (b) with a speed of 7.6 m/s while decelerating at a rate of 2.4 m lsz
