Homework Assignment: No credit will be given for problems without work. Please read the homework guidelines in the syllabus. Each question is worth 10 points. Applications of Newton's Laws 1. A sports car of mass 1000 kg can accelerate unifomly from rest to 27 m/s in 7.0 5. What is the forward force on the car? Three connected blocks are pulled to the right on a horizontal frictionless table by a force of magnitude T3 = 65.0 N . If m1 2120 kg, m2 = 24.0 kg , and m3 =3l.0 kg , calculate (a) the magnitude of the system's acceleration, (b) the tension 1'] , and (c) the tension T2 . A block of mass m1 = 3.70 kg is held on a frictionless plane inclined at angle 9 2 300 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 m1 and m2 (b) Find the magnitude and direction of the acceleration of each block (c) 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 1'32
