Question

What is conserved in an electric collision? A block is released from rest on the left side of each of the three friction ramps and slides along the ramp shown in the figure. On which ramp does the block reach the greatest height when it is on the righthand side? Consider air resistance negligible. A block rests on a horizontal frictionless table. It is attached to a spring and set into motion. At which point or points in the oscillation is the speed of the block greatest (circle only one choice) 4. (3 pts) A block rests on a horizontal frictionless table. It is attached to a spring, pulled away front the equilibrium point, and released so that it oscillates. Then the experiment is repeated, this time pulling the block twice as far from the equilibrium point before releasing it. Which of these will be greater the second time?

Explanation / Answer

1) c) both momentum and kinetic enrgy

2) d) same height for all ramps

3) a) when the block crosses equilibrium point

4) a) The maximum acceleration
