A 149-kg satellite is in circular orbit around the Earth and moving at a speed of 2.29 km/s. How much work must be done to move the satellite into another circular orbit that is twice as high above...

The moon takes 27.32 days to go around the Earth. Find the moon's angular velocity and its linear velocity. The moon is 3.84 x 10^8 meters from Earth.

Two gliders, A(.55kg) and B(.35kg) are held together by a string which compresses a spring between the gliders. The masses are traveling at 0.5m/s. a match burns the string and mass B is seen to be...

Suppose you are transporting a viscous fluid through a set of 15.0 circular pipes, each with diameter 1.0 cm. If you now replace this set of pipes with one large circular pipe which has a cross sectional...

A uniform clay disk with mass 3.5kg and radius 0.52m spins about its center of mass with an angular velocity of 19 rad/s counter-clockwise. If the disk is reshaped (without friction) into a uniform...

A small child weighing 201 N sits on a swing of length 2.4 m. Suppose that the child-swing system gradually slows down in such a way that on each successive swing the maximum y coordinate of the child's...

A) Eric is pushing a lever to lift a 20kg box which lies a distance of .5 meters from the fulcrum. Eric pushes down on the lever with 50N of force, what distance is Eric from the fulcrum?   B)...

Hey I'm i have a physics test in a few days and am really not understanding coefficients of friction and those type of questions. I'll give you an example of what I'm dealing with..    1)...

A bomber flying at an angle 30degrees below the horizontal with 240m/s velocity drops a bomb. A rocket launcher 300m directly below the bomber, fires a shell (at exactly the same time bomb was dropped)...

2) A boat traveling west encounters a current moving 8m/s south. The boat travels 56m downstream while crossing the 100m wide river. a) How much time does it take to travel shore to shore? b)...

There a mass of 4kg and a mass of 5kg connected by an inextensible string passing over a smooth pulley .the mass for 4kg starts from rest and moves up the smooth plane inclined at 30degree to horizontal...
