This question assesses the gravitational attraction due to a cylinder of mass. Consider a cylinder with radius R equal to the mean radius of the Earth, length L and a mass M equal to the mass of the Earth. The specific task is to determine the escape velocity from the end of the cylinder. First, though, consider a different but related problem: a particle with mass mp placed a distance r from the center of a ring of mass M,...

Please work out 3 clearly and with units. Thanks!
1. A 10-g bullet travels vertically upwards at 1000 m/s, then strikes and passes through a 2.0-kg block initially at rest. The bullet emerges from the block with a speed of 400 m/s because it transfers momentum to the block. (a) How much momentum did the block gain? (b) How fast is the block now moving, and what is its kinetic energy? (c) Using energy considerations only, to what maximum height...

I need the answers with steps please!
10. A boy throws a ball with an initial velocity of 25 m/s at an angle of 30° above the horizontal. If air resistance is negligible, how high above the projection point is the ball after 2.0s? How long is it in the air, and how far does it go before hitting the ground? 11. A projectile leaves the ground at 150 m/s and reaches a maximum height of 0.57 km. If there...
