Find the angular velocity of the earth as it spins on its axis and the tangential velocity of an object at the equator and one at the University of West Florida in Pensacola.
compute the tension in the rope if the gymnast slides down the rope with a downward acceleration of magnitude 1.40 m/s^2 .
Friction and air resistance are negligible. Illustrate what speed does the ball have when the cable makes an angle of 30 degrees with respect to the vertical?
A weightlifter has been given a barbell to lift. One end has a mass of 5.05 kg while the other end has a mass of 5.20 kg. The bar is 0.20 m long. (Consider the bar to be massless, and assume that the masses are thin disks, so that their centers of ma..
A grandfather's clock is calibrated at a temperature of 20 C. The pendulum is a thin brass rod with a heavy mass attached to the end. On a hot day, when the temperature is 30 C, does the clock run fast or slow? How much time does it gain or lose i..
If the coefficient of friction between the block and the floor is 0.40, what is the mass of the block.
Assume a small child rolls off a bed that is 0.38m above the floor. If the floor is hardwood, the child's head is brought to rest in approximately 2.2mm. If the floor is carpeted, this stopping distance is increased to about 1.1cm.
A 70kg man walks out on a 10kg beam that rests on, but is not attached to, two supports. When beam just starts to tip, what is the force exerted on the beam by the right support.
A 10 Newton effort force is required to lift a 10kg box just off the ground. What is the effort required to lift the box off the ground using a 3m long lever.
If the mass of a sliding block is tripled at the equal time the net on it is tripled, how does the resulting acceleration compare with original acceleration?
Write a general expression of the flux
A bungee jumper with mass 63 jumps from a high bridge. After reaching his lowest point, he oscillates up and down, hitting a low point eight more times in 47. He finally comes to rest 21.00 below the level of the bridge.
A 1.35 kg object is moving in the x direction at 16.4 m/s. Just 3.61 s later, it is moving at 28.8 m/s at 36.0^circ to the x axis. What is the magnitude of force applied throughout this time.
