Question

• Which of the following can be
obtained from speed - time
graph of a body?
(i)
Initial speed.
(ii) Final speed.
(iii) Distance covered in time t.
(iv) Acceleration of motion.​

Answer 1

Answer:

From speed-time graph of a body, we can calculate acceleration of the body and the distance travelled by the body.

Answer 2

Answer:

(a)Since velocity is not changing, acceleration is equal to zero.

(b) Reading the graph, velocity=20ms

−1

(c) s = area of the figure enclosed under v-t graph. Distance covered in 15s, s=ut=20×15=300m
