A child rolls a 0.600-kg basketball 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 basketball at the bottom of the ramp, it has a speed of 8.0 m/s. When the ball returns to her after rolling up the ramp […]

A 500.0-g bird is flying horizontally at 2.25 m/s, not A 500.0-g bird is flying horizontally at 2.25 m/s, not paying m A 500.0-g bird is flying horizontally at 2.25 m/s, not paying much attention, when it suddenly flies into a stationary vertical bar, hitting it 25.0 cm below the top (Fig. 10.63). The bar […]

A centrifuge rotor rotating at 10,300 rpm is shut off 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 the rotor is 4.80 kg and it can be approximated as a solid cylinder of radius 0.0710m, […]

A centrifuge rotor has a moment of inertia of 3.75 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? Is this the question you were looking for? If so, place your order here to get started!

A car starts from rest and moves around a circular 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 magnitude of its net linear acceleration 15.0 s later? (b) What angle does this net acceleration […]

A bicycle odometer (which measures distance traveled) is attache A bicycle odometer (which measures distance traveled) is attached near the wheel hub and is designed for 27-inch wheels. What happens if you use it on a bicycle with 24-inch wheels? Is this the question you were looking for? If so, place your order here to […]

A block with mass m is revolving with linear speed 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 slowly pulled from below until the radius of the circle in which the block is revolving is […]

A Ball Rolling Uphill, A bowling A Ball Rolling Uphill, A bowling ball rolls without slipping up a ramp that slopes upward at an angle p to the horizontal (see Example 10.7 in Section 10.3). Treat the ball as a uniform, solid sphere, ignoring the finger holes. (a) Draw the free-body diagram for the ball. […]

A bicyclist of mass 70 kg puts all his mass A bicyclist of mass 70 kg puts all his mass on each downward- moving pedal as he pedals up a steep road. Take the diameter of the circle in which the pedals rotate to be 0.40 m, and determine the magnitude of the maximum torque […]
