QUESTION 2
Two learners are pushing another learner from rest in a westward direction on a cart as seen in
the diagram below:
2.1 Define resultant force. (2)
2.2 Draw a vector diagram to illustrate all the forces on the cart. (3)
2.3 Determine the magnitude of and direction of the resultant force on the cart. (3)
2.4 If the cart is accelerating at a speed of 1,2m.s -2 determine how long it would take
the cart to complete 100 meters. (4)
[12]
QUESTION 3
Two vehicles A and B are approaching a traffic light intersection at 55km/h.
The light turns orange when they are 30m from the intersection.
Vehicle A puts on its brakes and slows down to stop at the intersection while vehicle B accelerates
at 4 m.s-2 through the intersection for 3 seconds before continuing at a constant velocity.
3.1 Define velocity. (2)
3.2 Convert 55km/h to m.s-1. (2)
3.3 Did vehicle B drive through the intersection while the light was yellow or red?
Assume a yellow light only lasts 5 seconds. (1)
3.4 Calculate the acceleration of vehicle A as it slows down to stop. (3)
3.5 Calculate the final constant velocity of vehicle B. (3)
3.5 Sketch a velocity-time graph for both vehicles on the same set of axes.
Be sure to label all the relevant values. (5)
