1700 kg satellite is orbiting the Earth in a circular orbit with an altitude of 1700 km
1) how much energy does it take to get it to this altitude
2)how much kinetic energy does it have once it has reached this altitude
3)what is the ratio of this change in potential energy to change in kinetic energy
4)what would this ratio be if the final altitude of the satellite was 4700 km
5)what would be this ratio if the final altitude was 3185 km?

A 10 g bullet is fired with 450 m/s into a 10 kg block that sits at rest on a wooden table 20 cm from the edge of the table. The bullet gets embedded in the block (perfectly inelastic collision). The block, with the embedded bullet, then slides to the edge of the table and drops down with some initial velocity while leaving the edge of the table. The coefficient of kinetic friction between the block and the surface of...

A 2.0-kg ball moving at 10 m/s makes an off-center collision with a 3.0-kg ball that is initially at rest. After the collision, the 2.0-kg ball is deflected at an angle of 30° from its original direction of motion and the 3.0-kg ball is moving at 4.0 m/s. Find the speed of the 2.0-kg ball and the direction of the 3.0-kg ball after the collision. Hint: sin2θ + cos2θ = 1. speed of 2.0-kg ball m/s direction of 3.0-kg ball...

An object of 4 kg (assuming the acceleration of gravity g = 10 m / s2 ) suspended from a spring causes the spring to stretch 2 cm downwards. The object is moved 3 cm down from from its equilibrium position in the positive direction of movement, then it is released with speed zero initial. Assuming that there is no damping and that the object is under external force equal to: 20cos4(t) (N) a) Formulate the initial value problem that...
