V = 4 m/s ac μ= 0.1 Center of rotation R = 20 m Car around corner A 400 kg car is going around a curb as shown. The radius of the turn is 20 m and the car has a velocity of 4 m/s. The coefficient of friction between the tires and the road is 0.1 a. What is the angular velocity of the car? a. Will the car make the turn?

You and your friend ride a merry-go round. You sit further away from center (2r) but your friend sits closer to the center (r). If the angular speed of the system is a constant, what can you say about following for you and your friend?a. linear speed? b. Angular speed?c. radial acceleration?b. tangential acceleration? 2c. if the ride starts with zero angular speed and run with constant angular acceleration of 2.00 rad/sradius 4m circle., calculate final angular displacement and linear displacement you and your friend travel?

Josh is painting yellow stripes on a road using a paint roller. To roll the paint roller along the road, Josh applies a force of 15 N at an angle of 45° with respect to the road. The mass of the roller is 2.5 kg; and its radius is 4.0 cm. Ignoring the mass of the handle of the roller, what is the magnitude of the tangential acceleration of the roller?   A. 4.2 m/s2   B. 6.0 m/s2   C. 15 m/s2   D. 110 m/s2
