Question

A particle moves in a straight line with initial velocity 4 m/s and a constant acceleration of 6 m/s2 . Find the average velocity of the particle in a time interval from :
(a) t = 0 to t =2
(b) t = 2s to t = 4s

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.

2.

1

t.5.t+(25−2t).5t=500=>t

2

−25t+100

=>t=5

so option B is answer.
