In the figure, a cord runs around two massless, frictionless pulleys; a canister with mass m = 25 kg hangs from one pulley; and you exert a force F on the free end of the cord. What must be the magnitude of F if you are to lift the canister at a constant speed?
Here i know that the answer is...
another quick question. There is a ramp at an angle now a box is being pushed up with certain force up a certain distance. The mass of the block is given. How can i figure out what the total work done is?
a constant force of magnitude 10 N makes an angle of 150. (measured counterclockwise) with the direction of increasing x as the force ascts on the 2 kg object. how much work is done on the object by the force as the object moves from the origin to the point with position vector. (2m)i - (4m)j...
Hi this question is from past IB exam. I tried to solve it but i am not getting the right answer. Could someone please help me on this thanks a lot.
A block with mass m = 21.1 kg slides down an inclined plane of slope angle 13.3 ° with a constant velocity. It is then projected up the same...
