Question

The velocity-time graph shows the motion of cyclist. Find a) its acceleration b) its velocity c) distance covered by cyclist in 15 seconds

Answer 1

Answer:

Acceleration is zero as body is moving with constant/uniform velocity.

Distance Covered = V × t = 20 × 15 = 300m

Velocity is uniform and 20 m/s.

Answer 2

Answer:

300 m

Explanation:

In the above v-t graph velocity is constant so there is no acceleration.

b. its velocity = 20 m/s

we have,

acceleration = 0

time = 15s

initial and final velocity = 20m/s

c. distance(s)

we have,

acceleration = 0

time = 15s

initial and final velocity = 20m/s

we can use the second equation of motion

that is s = ut + 1/2 at²

20 * 15 + 1/2 * 0 * 15²

= 300 m + 0

= 300m

hope this helps!!!
