The box was initially at rest. A force of 150 N was applied, causing the box to move at constant velocity.
(a) What is the resultant force of the box?
(b) State the magnitude of the frictional force.
(c) When force applied is increased to 200 N, calculate the acceleration of the box.
(d) Calculate the velocity of the box after 5 seconds.
(e) What is the distance travelled by the box in the 5 seconds.
