Question

Find the answers of the questions given below

Answer 1

Acceleration :

• Velocity does not change
• Hence,
  `\boxed {a = 0 m/s^(2)}`

Velocity :

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

Distance :

• Use the formula,
  `\boxed {S = v * t}`, as velocity is constant
• S = 20 × 15
• 
  `\fbox {S = 300 m}`

Answer 2

i)
`0m/s^(2)`

ii)20m/s

iii)300m

Step-by-step 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 =
`0m/s^(2)`

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
