A soccer ball of mass 0.39 kg is rolling with velocity <0, 0, 2.4> m/s, when you kick it. Your kick delivers an impulse of magnitude 2.4 N·s in the -x direction. The net force on the rolling ball, due to the air and the grass, is 0.32 N in the direction opposite to the direction of the ball's momentum. Using a time step of 0.5 s, find the position of the ball at a time 1.5 s after you...

The mass of the symmetrical wheel shown below is m = 4 kg and its radius of gyration about its center is kg = 0.25 m. The outer radius of the wheel is r2 = 0.4 m. The radius of the inner hub, where a cable is wrapped around it, is rı = 0.2 m. The wheel rolls without slipping. The force P, applied to the cable, is increased slowly according to the linear relation P = at, where P...

2. A block of 3 kg is sitting at rest on an incline of 10 degrees. A constant pushing force of 40 N is applied in the uphill direction for 1.3 seconds. The incline also provides a constant friction force of 20 N. Use the impulse-momentum approach to calculate how long the block will continue to slide before it comes to a stop on the incline.
