Problem
A horizontal force of 40 N is applied to a 5 kg crate by pushing on it with a rod that makes an angle 20° below the horizontal. The coefficient of kinetic friction between the crate and the floor is 0.25.
(a) Find the acceleration of the crate while the force is acting.
(b) If the force continues for 4.0 s starting from rest, calculate the distance travelled in this time.
