Question

A crate of mass 40.0 kg is pulled by a force of 2000 N, up an inclined plane which
makes an angle of 30º with the horizon. The coefficient of kinetic friction between the
plane and the crate is k = 0.20. If the crates starts from rest, calculate its speed after it
has been pulled 10.0 m. Draw the free body diagram. Take
10.0 ms .

Answer 1

Answer:

Average speed is defined as the average distance travelled per unit time and is obtained by dividing the total distance travelled by the total time taken.
