MULTIPLE CHOICE QUESTION

3 mins • 1 pt

A ball is released from spring that pushes a 0.5kg ball over a 2cm distance and accelerates the ball to 2m/s2 every time. If the ball is sprung toward a ramp of 450 and then again at a ramp of 200, how high up will the ball travel above the horizon on each ramp relative to each other?

higher on 450 ramp

higher on 200 ramp

the same height

not enough information to answer

A ball is released from a spring that pushes a 0.5kg ball over a 2cm distance and accelerates the ball to 2m/s2 every time. If the ball is sprung toward a ramp of 450 and then again at a ramp of 200, how will the displacement up each ramp compare?

displacement will be the same

the displacement will be greater on the 200 ramp

the displacement will be greater on the 450 ramp

the displacement will be equal but it will travel higher on the 450 ramp

A ball is released from spring that pushes a 0.5kg ball over a 2cm distance and accelerates the ball to 2m/s2 every time. If the ball is sprung toward a ramp of 450 and then again at a ramp of 200, how does the potential energy of the ball on the ramps (at the ball's highest point) compare to each other?

greater on 200 ramp

greater on the 450 ramp

the same on each ramp

A ball is released from a spring that pushes a 0.5kg ball over a 2cm distance and accelerates the ball to 2m/s2 every time. If the ball is sprung toward a ramp of 450 and then again at a ramp of 200, how does the acceleration change as the ball moves upward compare on each ramp?

acceleration changes faster on 45o ramp

acceleration changes faster on 20o ramp

acceleration change is same on each ramp

can't answer because we don't know the time it takes for ball to stop rolling.

A ball is released from a spring that pushes a 0.5kg ball over a 2cm distance and accelerates the ball to 2m/s2 every time. If the ball is sprung toward a ramp of 450 and then again at a ramp of 200. When the ball reaches its' highest point on the ramp, which system has the greatest potential energy?

the 20o ramp system

the 45o ramp system

neither system

the potential energy is not predictable
