Abowling ball of mass m and radius r is thrown such that at the instant it touches the floor it is moving horizontally with a speed vo and is not rotating. it slides for a time a. if heis the coefficient of sliding friction between the ball and the floor, find s, c. find the ratio of the final mechanical energy to the initial mechanical energy of t1 a distance s, before it begins to roll without slipping. t1 and the final speed v1 of the ball. b. evaluate these quantities for vo -8m/s and u 0.06. the ball.

If a stone with an original velocity of 0 is falling from a ledgeand takes 8 seconds to hoybthe ground whays the final velocity of the stone

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?
