Block on a Slope
(a) Start with block 1. It starts at rest, then accelerates a distance
of 16 m in a time of 4.2 seconds. Use equation from kinematics:
Acceleration of block 2 is just the same as acceleration of block
1! All objects fall with approximately the same acceleration.
(b) We have a relation between final and initial velocities, :
and so we get .
(c) Half the time is spent coming down from the highest point. So
the time to "fall'' is 2.1s. Distance traveled is again from
