Physics
A 2050 kg car rounds a circular turn of radius 18.5 m. If the road is flat and the coefficient of friction between tires and road is 0.680, how fast can the car go without skidding?

Physics
The flywheel of a steam engine begins to rotate from rest with a constant angular acceleration of 1.39 rad/s^2. It accelerates for 30.3 s, then maintains a constant angular velocity. Calculate the total angle through which the wheel has turned 69.1 s after it begins rotating.

Physics
A tire placed on a balancing machine in a service station starts from rest and turns through 4.71 revolutions in 1.29 s before reaching its final angular speed. Calculate its angular acceleration.

Physics
A 0.300 kg puck, initially at rest on a frictionless horizontal surface, is struck by a 0.215 kg puck that is initially moving along the x axis with a velocity of 2.14 m/s. After the collision, the 0.215 kg puck has a speed of 1.14 m/s at an angle of q = 53.5 deg to the positi...

physics
A dentist's drill starts from rest. After 3.62 s of constant angular acceleration it turns at a rate of 2.70E+4 revolutions per minute. Find the drill's angular acceleration. Determine the angle through which the drill rotates during this period.

physics
4. A rat named Littleguy runs in a treadmill (a wire wheel) with a diameter d =8.00 inches. In 5.00 minutes, Littleguy makes the treadmill rotate 2.80 x 10² times. If the rat were running along the ground, how far would he have run? What was his average velocity?
