A bicyclist traveling with speed v = 4.2 m/s on a flat road is making a turn with a radius r = 6.4 m. The forces acting on the cyclist and cycle are...

A block with mass m = 5.00 kg slides down a surface inclined 36.90 to the horizontal (Fig. 10.55). The coefficient of kinetic friction is 0.25. A...

A block with mass m is revolving with linear speed v, in a circle of radius r, on a frictionless horizontal surface (see Fig. 10.48). The string is...

A bowling ball of mass 7.3 kg and radius 9.0 cm rolls without slipping down a lane at 3.3m/s. Calculate its total kinetic energy.

A car starts from rest and moves around a circular track of radius 30.0 m. Its speed increases at the constant rate of 0.500 m/s2 (a) What is the...

A centrifuge accelerates uniformly from rest to 15,000 rpm in 220s. Through how many revolutions did it turn in this time?

A centrifuge rotor has a moment of inertia of 3.75 x 10-2 kg m2. How much energy is required to bring it from rest to 8250 rpm?

A centrifuge rotor rotating at 10,300 rpm is shut off and is eventually brought uniformly to rest by a frictional torque of 1.20 m N. If the mass of...

A child rolls a 0.600-kg basketball up a long ramp. The basketball can be considered a thin-walled, hollow sphere. When the child releases the...

A child rolls a ball on a level floor 3.5m to another child. If the ball makes 15.0 revolutions what is its diameter?
