Question

A car travelling at 10ms ,acceleration uniformly at 2ms what will be its velocity after 5s?​

Answer 1

20 ms

Step-by-step explanation:

You know

acceleration=2ms initial Velocity=10ms Time=5s

We are finding Final V

Use the equation Final v = (a x t) + initial v

2 x 5 = 10

10 + 10 = 20

Answer 2

`we \: know \: that \\ acceleration = ((final \: velocity - initial \: velocity))/(time) \\ = > a = ((v - u))/(t) \\ = > 2m {s}^( - 2) = \frac{{(v - 10m {s}^( - 1) })}{5s} \\ = > 2m {s}^( - 2) * 5s = v - 10m {s}^( - 1) \\ = > 10m {s}^( - 1) = v - 10m {s}^( - 1) \\ = > 10m {s}^( - 1) + 10m {s}^( - 1) = v \\ = > 20m {s}^( - 1) = v \\ = > 20m {s}^( - 1) = initial \: velocity`

Hope it helps!!

Thanks!!
