Question

The velocity-time (v-t) graph of a particle_moving
along x-axis is as shown. Choose the correct
statement
17 Acceleration of the particle continuously
decreases
(24 Displacement of the particle continuously
increases
(3) Acceleration remains constant
Y4) Both (1) and (2)​

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.

2

1

​

t.5.t+(25−2t).5t=500=>t

2

−25t+100

=>t=5

so option B is answer.

Answer B
