A ball and bat, approaching one another each with the same speed of1.7 m/s, collide.
1. Discover the speed of the ball after the collision. (Suppose the mass of the bat is very much larger than the mass of the ball, a perfectly elastic collision, and no rotational motion).
2. Discover the factor by which the kinetic energy of the ball increases due to the collision
A sled weighs 100N. It is held in place on a frictionless 20 degrees slope by a rope attached to a stake at the top, the rope is parallel to the slope. What is the normal force of slope acting on the sled.
An artificial satellite circles the Earth in a circular orbit at a location where the acceleration due to gravity is 5.24 m/s^2.
A 5.00 g bullet is fired into a 500g block of wood suspended as a ballistic pendulum. What was the magnitude of the momentum of the combined mass immediately after the collision
An adventurous archaeologist crosses between two rock cliffs by slowly going hand over hand along a rope stretched between the cliffs. He stops to rest at the middle of the rope (See the figure). The rope will break if the tension in it exceeds 3.00×..
