Question

A particle is travelling along a straight line. Its position-time graph is given below. Study the graph carefully and find the velocity of the particle for the following time intervals: (i) 0s to 5s, (ii) 5s to 10s, (iii) 10s to 15s, (iv)0s to 15s.

Answer 1

Answer:

(I) 1m/s

(II) 2m/s

(III) 0m/s

(iv) 1m/s

Explanation:

velocity =displacement /time

(I) displacement =5m and time=5sec

there for velocity is 1 m/s

(II) displacement =10m and time=5sec

there for velocity is 2 m/s

(III) displacement =0m and time=5sec

there for velocity is 0 m/s

(iv) displacement =15m and time=15sec

there for velocity is 1 m/s
