A 4.25g bullet traveling horizontally with a velocity of magnitude 375m/s is fired into a wooden block with mass 1.10kg , initially at rest on a level frictionless surface. The bullet passes through the block and emerges with its speed reduced to 126m/s
How fast is the block moving just after the bullet emerges from it?
v = ? m/s
You are to drive to an interview in another town, at a distance of 300 km on an expressway. The interview is at 11:15 a.m. You plan to drive at 100 km/h, so you leave at 8:00 a.m. to allow some extra time. You drive at that speed for the first 110..
