The velocity-time (v-t) graph of a particle moving along a straight line is shown below. Find the average velocity of the particle in kmh. [3] 100 Velocity (ms) 100 50 Time (S) -> - 2 -
Answers
Explanation:
Correct option is B)
average velocity is 25m/s so distance will be 25×20=500m
now finding area of the graph between velocity and time graph we get
area of two triangles + area of rectangle.
2.
2
1
t.5.t+(25−2t).5t=500=>t
2
−25t+100
=>t=5
so option B is answer.
