Question

What is the acceleration of the car in initial 2 seconds [ans:20m/s^2

Answer 1

20 m/s^2

Step-by-step explanation:

v = u + at

Velocity:-

u = 0

v2 = 40

v = v2 - u = 40 - 0 = 40

Time:-

t2 = 2

t1 = 0

t = t2 - t1 = 2 - 0 = 2

Substituting v and t in formula,

v = u + at

40 = 0 + (a)(2)

2a = 40

=> a = 40/2

=> a = 20

Answer 2

`accelaration = (v)/(t) \\ = in \: intial2sec \: v = 40 \\ a = (40)/(2) = 20 \frac{m}{ {se}^(2) } \\ thank \: you`
