What is the acceleration of a 0.30-kg volleyball when a player uses a force of 42 N to spike the ball?

A 85-kg astronaut is stranded from his space shuttle. He throws a 1-kg hammer away from the shuttle with a velocity of 17 m/s. How fast will he be propelled toward the shuttle, in m/s? (Round your answer to one decimal place if necessary.)

What is the modern Jatomic theory?

There is a potential energy associated with gravitational andspring forces. Is there also a potential energy associated withfrictional forces? A.

Two piers, A and B, are located on a river: B is 1500 m downstream from A (Figure 1). Two friends must make round trips from pier A to pier B and return. One rows a boat at a constant speed of 4.

Both gravitational potential energy and kinetic energy depend on

Suppose a body has a mass of 60 kilograms and a velocity of 2 meters per second upward. What is the linear momentum?

Reflection and abssorption prevent some

Why is it important to change only one experimental variable at a time in an experiment?
