QUESTION 2 QUESTION 2 A 5 kg bоx full оf reаding bоoks is projected upwаrds on а slope with an initial velocity of 2 m.s-1, as shown below. After a specific period of time, the box comes to a standstill. The coefficient of kinetic friction between the surface and the box is 0.18. 2.1 Define Newton's Second Law of Motion in words. (2) 2.2 Draw a free body diagram of all the forces acting on the box. (3) 2.3 Determine the friction between the box and the surface, as it moves upwards against the slope. (5) 2.4 Determine the net force exerted on the box as it moves up the slope. (4) 2.5 Calculate the distance that the box with books has moved up the slope using equations of motion and the law as defined in Question 2.1. (6) 2.6 If an applied force of 100N is applied to the right, parallel to the surface of the box, how will this affect the coefficient of kinetic friction? Write only INCREASE, DECREASE OR REMAIN THE SAME. (1) [21] Please do not submit any answers in the block below.
