A 20 g bullet traveling at 300 m/s is shot into a 4.0 kg block at rest on a frictionless horizontal surface. The bullet remains lodged intothe block
a) What is the speed of the block right after shooting?
b) The block then slams into an ideal spring moving horizontally ona frictionless floor. The spring constant of the spring is 2400 N/m. What is the maximum compression of the spring?
c)If the floor is rough and has a coefficent of kinetic friction of -0.45, what is the maximum compression of the spring?
For safety in climbing, a mountaineer uses a nylon rope that is 60 m long and 1.0 cm in diameter. When supporting an 88 kg climber, the rope elongates 1.80 m. Find its Young's modulus.
The rope is inclined at 20.30° above the horizontal, and the sledge moves a distance of 20.3 m on a horizontal surface. The coefficient of kinetic friction between the sledge and surface is 0.500.
