1 In the figure, block 1 has mass M1, block 2 has mass M2, the pulley has inertia I and radius R, and the angle of the hill is 0 measured to the horizontal. The horizontal part of the hill has no friction, but the slope has coefficient u. Write down the equations that give the acceleration of the system. You don't have to solve them, just write them down in an organized form. There are 4. 2.
1. A wheel is spinning so that it goes around 6 times every second. A brake is then applied to the wheel, causing it to slow to a frequency of 3 times per second in 5 seconds. How many times does the wheel spin around while the brake is applied? Fill in the table with what is given and what is needed. All values in the table should be in terms of radians. ΔΘ @i Of а At X
