A stone, which weighs 0.62kg, is thrown, at 5.5ms, its kinetic energy at its maximum height above the surface is 2.3J, what is the height of the stone at this point? Any eqautions or advice gratefully recieved. I assume that is 5.5 m/s, the initial velocity. Ok, assuming that...

I assume that you mean the bucket is tied to a rope and the rope is swung in a circular arc, up and down like a ferris wheel. The bucket and the water are force to undergo centripetal acceleration. If the motion is fast enough, the centripetal acceleration of the water at the ...

A pilot flies an airplane in a vertical circular loop at a constant speed ő = 160 m/s. If the pilot’s apparent weight at the top of the loop is one-third of his true weight when he is on the ground, find the radius R of the plane’s circular path. answer is 1960 m but i need ...

Write equations of motion for the horizontal and vertical coordinates. Hasn't someone done that for you before? (a) Solve the vertical motion equation for the time when the altitude is 0. The initial altitude is 97 m. The initial velocity will not matter in this case, since it...
