Question
Nancy measures the speed of the wooden block after it has gone the 1.95 m down the ramp. Predict what speed she
should measure.
final speed after sliding from rest:
m/s
Now, Steven again places the wooden block back at the top of the ramp, but this time he jokingly gives the block a big push
before it slides down the ramp. If the block's initial speed is 2.00 m/s and the block again slides down the ramp 1.95 m, what
should Nancy measure for the speed of the block this time?
final speed after sliding with initial speed 2.00 m/s:
m/s
