Pressure is defined as the force per unit area on a body.
Answer:
10.8rev
Explanation:
Using
Wf²-wf = 2 alpha x theta
0²- 56.36x56.36/ 2(-20.13) x theta
Theta = 68.09 rad
But 68.09/2π
>= 10.8 revolutions
Explanation:
The force acting on the boulder bringing it down the mountain? Would be gravity. Not sure about any of the multiple choice options you have
The static frictional force is greater than the kinetic frictional force, so the static frictional force is greater than 1200 N.
It's the measure of the average kinetic energy
