Answer:
8. acceleration = [tex]\dfrac{d(velocity)}{d(time)}[/tex] = 1 unit .
9. acceleration = [tex]\dfrac{d(velocity)}{d(time)}[/tex] = -1 unit.
10. acceleration = [tex]\dfrac{d(velocity)}{d(time)}[/tex] = 0 units.
Explanation:
8. i) acceleration = velocity / time
ii) In this figure velocity = time
iii) therefore acceleration = [tex]\dfrac{d(velocity)}{d(time)}[/tex] = 1 unit .
9. i) acceleration = velocity / time
ii) In this figure 4 = m + 5, therefore m = -1
therefore velocity = (-0.5 [tex]\times[/tex] time) + 5
iii) therefore acceleration = [tex]\dfrac{d(velocity)}{d(time)}[/tex] = -1 units.
10.) velocity is constant at 2
therefore acceleration = [tex]\dfrac{d(velocity)}{d(time)}[/tex] = 0 units
