A spherically symmetric object, with radius R = 0.700 m and mass M = 1.90 kg, rolls without slipping across a horizontal floor, with velocity V = 1.200 m/s. It then rolls up an incline with an angle of inclination θ = 40.0 deg and comes to rest a distance d = 0.177 m up ...
A flywheel comprises a uniform circular disk with a moment of inertia of 64.13 Kg m2. It rotates with an angular velocity of 1106. rpm. A constant tangential force is applied at a radial distance of 0.400 m. What energy (in Kilo Joule) must this force dissipate to stop the ...
A uniform ladder of mass m is 2.5 m long. Its upper end leans against a frictionless wall. The coefficient of static friction between the ladder and the floor is 0.58. How far from the wall can the lower end be placed before the ladder starts to slip? Hint: for the ladder to ...
A drunken driver crashes his car into a parked car that has its brakes set. The two cars move off together (perfectly inelastic collision), with the locked wheels of the parked car leaving skid marks 6.0 m in length. If the mass of the moving car is 2130kg and the mass of the ...
A boy in a wheelchair (total mass, 46.0kg) wins a race with a skateboarder. He has a speed of 1.33m/s at the crest of a slope 2.24m high and 13.2m long. At the bottom of the slope, his speed is 6.35m/s. If air resistance and rolling resistance can be modeled as a constant ...
