an
ice puck of mass m revolves on an icy surface in a circle at speed
v at the end of a horizontal string of length L. the tension in the
string is T.
write the equation for centripetal force, and substitute the
values T and L appropriately. then with a bit of elementary
algebra, rearrange the equation so that it solves for mass.

1)A toy car with a mass of 4 kg is driving up an inclined ramp. It starts at a speed of 3 m/s, and after it has traveled a distance of 2 m up the ramp it comes to a stop. How much total work was done on the toy car? 2)A girl lifts a 1 kilogram box vertically a distance of 1 meter, at constant speed. What is the total work done on the box (rounded to 1 significant...

You push a crate of mass m up a ramp inclined at an angle A with a force parallel to the ramp but of varying magnitude. The coefficient of friction between the crate and ramp is u, and the speed of the crate, which starts from rest, is v at the end of the ramp of length d. a) Use the work-energy theorem to find the work done by the non-constant force in moving the crate up the ramp. b)...
