Consider a father pushing a child on a playground merry-go-round. The system has a moment of inertia of 84.4 kg · m2. The father exerts a force on the merry-go-round perpendicular to its 1.50 m radius to achieve a torque of 375 N · m. (a) Calculate the rotational kinetic energy (in J) in the merry-go-round plus child when they have an angular velocity of 10.0 rpm. ___J (b) Using energy considerations, find the number of revolutions the father will...

Calculate the maximum acceleration (in m/s2) of a car that is heading down a 6.290 slope (one that makes an angle of 6.290 with the horizontal) under the following road conditions. You may assume that the weight of the car is evenly distributed on all four tires and that the static coefficient of friction is involved-that is, the tires are not allowed to slip during the acceleration. (Ignore rolling friction. Assume the positive direction is down the slope. Indicate the...
