Answer:

i)[tex]0m/s^{2}[/tex]

ii)20m/s

iii)300m

Explanation:

In this Velocity-Time graph,

i) The acceleration can be found by finding the slope of the graph, which in this case, since it is a horizontal line, the slope = 0 therefore the acceleration = [tex]0m/s^{2}[/tex]

ii)The velocity can be found on the y-axis, in this case, is 20m/s.

iii)The distance covered can be found by finding the area of the graph to the corresponding time. In this case,

t=15

Distance covered = 20m/s * 15s

= 300m

Acceleration :

  • Velocity does not change
  • Hence, [tex]\boxed {a = 0 m/s^{2}}[/tex]

Velocity :

  • According to the graph, the cyclist has a constant velocity of 20 m/s
  • [tex]\fbox {v = 20 m/s}[/tex]

Distance :

  • Use the formula, [tex]\boxed {S = v \times t}[/tex], as velocity is constant
  • S = 20 × 15
  • [tex]\fbox {S = 300 m}[/tex]
