Question

4. The velocity-time graph shows the motion of the cyclist. Find () its acceleration (3) its velocity
(iii) the distance covered by cyclist in 15 sec.​

Answer 1

Answer:

1) zero

2) 20

3) 300 unit

Step-by-step explanation:

1) since velocity is constant so acceleration will be zero.

2) constant velocity is 20 unit

3) v= ds/dt

so ds= integration v.dt

i.e. area under graph v and t

are= distance= 20×15= 300 unit
