Question

the speed-time graph of a body is shown in the following fig.calculate :(a) acceleration of the body.(b) total distance travelled by the body​

Answer 1

Acceleration of body is constant.
Here velocity(v) =9 when time(t) =4

For given points, a=v/t=9/4=2.25metre per second square

While d=v(t) =9(4)=36 meters

Answer 2

Answer:-

(1) Acceleration = v/t

As u is constant here ,

=> 9/4 = 2.25

=> 2.25 m/s^2

(2)

Let distance be ‘d’

=> d = 4*9 = 36m

Hope this helps :D
