Question

The speed-time graph of a particle moving along
a fixed direction is shown in the figure. The
distance traversed by the particle between
t=2s to t = 6 s is


(1) 26 m

(2) 36 m

(3) 46 m

(4) 56 m​

Answer 1

Answer:

Distance travelled by the particle = Area under the given graph. Let s1 and s2 be the distances covered by the particle between time t = 2 s to 5 s and t = 5s to 6 s respectively. a1 be the acceleration of the particle in t = 0 to t = 5s. The particle undergoes uniform acceleration in the first 5 seconds.

Answer 2

21×1.2+24−1.2×36+1.2×25

25.2+24−43.2+30=36m

(b) 36 m
