Question

12. 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 km/h.
​

Answer 1

Answer:

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.

1

t.5.t+(25−2t).5t=500=>t

2

−25t+100

=>t=5
