Question
A crate slides up a frictionless slope. At the end of 3 seconds its velocity is 20.0m/s; at the end of 8 seconds
its velocity is 0 m/s. What is the angle of the slope.
Top Answer
To find the slope, we first need to find the acceleration a. Thus, a = (v 2 -v 1 )/(t 2 -t 1 ) = (0-20)/(8-3) = -4 m/s 2 .... View the full answer
