A fun-loving 10.1kg otter slides up a hill and then back down to the same place.
If she starts up at 5.80 m/s and returns at 3.75 m/s , how much mechanical energy did she lose on the hill?
Explain how much work does the gravitational force do on the block as the block travels from point P to (a) point Q and (b) the top of the loop?
An 8.00 gram bullet is fired into a 250gm block that is initially at rest at the edge of a table of height 1.0 m. The bullet remains in the block, and after the impact the block lands 2.0 meters from the bottom of the table. Find out the initial s..
determine the generating function for the transformation q=Q+Pt, p=P. Show that the hamiltonian H(p,q)=p^/2 + V(q) transforms to H'(P,Q)=V(Q+Pt)
F = G.Mm/r2 where F is the gravitational force, M and m are masses, and r is a length. Force has the SI units kg · m/s2. What are the SI units of the proportionality constant G
