Mechanical (sound) waves to Earth from satellites. How is this possible? aves are unable to travel through a vacuum, such as through space, but radio waves are transmitted

An 80 kg hockey player is skating at 5 m/s. He collides with the wall and comes to a stop in. 2 s. What was the force of his impact on the wall

Part complete during a collision with a wall, the velocity of a 0.200-kg ball changes from 20.0 m/s toward the wall to 12.0 m/s away from the wall. if the time the ball was in contact with the wall was 60.

The power of a machine measures A. its rate of doing work. B. its strength. C. the force it produces. D. the work it does.

the acceleration of gravity is 28 times on sun than earth. Imagine there is a space suit that let you stand on sun. Calculate the weight of 100 kg person on earth in newtons

A force of 20 n acts upon a 5 kg block, calculate acceleration of the object
