Car B turns such that its speed is increased by (Q.)=(0.5e)m/s, where t is in seconds. If the car starts from rest when =0°, determine the magnitude of its velocity and acceleration when the arm AB rotates =30°. Neglect the size of the car. (Note: using tangent and normal components to solve this problem)
The small cylinder C has a mass of 10 kg and is attached to the end of a rod whose mass may be neglected. If the frame is subjected to a couple M = (8t² + 5) Nm where t is in seconds, and the cylinder is subjected to a force of 60 N, which is always directed as shown, determine the speed of the cylinder (in m/s) when t=2 seconds. The cylinder has a speed of vo 2m when...
