6. A spring whose spring constant is 850 N/m is compressed 0.40 m. What is the maximum speed it can give to a 0.50 kg ball?
A) Quantitative Energy Conservation Equation:
B) Determine the maximum speed.

Diamond will scratch quartz. true or false

The average density of the planet uranus is 1.27 103 kg/m3. the ratio of the mass of neptune to that of uranus is 1.19. the ratio of the radius of neptune to that of uranus is 0.969. find the average density of neptune.

Aball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. if the ball hits the floor with a speed of 2.40 m/s and rebounds with a speed of 1.70 m/s, determine the following. (a) magnitude of the change in the ball's momentum (let up be in the positive direction.)
