Chapter 2 & 3 Assignment 1. The diagram below shows a block of mass m resting on a 20° slope. The block has coefficients of friction H, = 0.80 and H = 0.50 with the surface. It is connected via a massless string over a massless pulley to a hanging block of mass 2.0 kg. a) What is the minimum mass m that will stick and not slip up the slope? 20° 2.0 kg b) If the minimum mass is nudged ever so slightly, it will start being pulled up the incline. Determine the magnitude of acceleration and tension along the rope. 2. In an amusement park ride, passengers stand inside a 16 m diameter rotating ring. After the ring has acquired sufficient speed, it tilts into a vertical plane, as shown in the diagram. a) Suppose the ring rotates once every 4.5 s. If a rider's mass is 55 kg, with how much force does the ring push on her at the top of the ride? Rotation axis b) At the bottom of the ride? 3. Imagine a car is turning around a corner, it will slide off the road if it is turning at a very fast speed. Use what you have learned about friction and circular motion to explain why.

1. The diagram below shows a block of mass m resting on a 20° slope. The block has
coefficients of friction H, = 0.80 and H = 0.50 with the surface. It is connected via a
massless string over a massless pulley to a hanging
block of mass 2.0 kg.
a) What is the minimum mass m that will stick and not
slip up the slope?
20°
2.0 kg
b) If the minimum mass is nudged ever so slightly, it will start being pulled up the incline.
Determine the magnitude of acceleration and tension along the rope.

a) Suppose the ring rotates once every 4.5 s. If a rider's
mass is 55 kg, with how much force does the ring push
on her at the top of the ride?
Rotation
