A modern F1 car can accelerate from 0 to 62 mile/h (100km/h) in 2.50 s. What is the angular acceleration of its 170 mm-radius wheels?
0-3 (65.17 rads)

Students design a model roller-coaster track. they place a rubber ball at the highest point on the track and let it go. the ball rolls along the track pulled only by the force of gravity. eventually, it comes to a stop. which change to the design will result in the ball moving the greatest distance?

What is the coefficient of kinetic friction μk between the block and the tabletop?

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
