Question

If a car accelerates from a speed of 10 m/s at an acceleration of 2 m/s2 for 3s.

Calculate the final speed of the car

Answer 1

`\boxed{\sf Final \ speed \ of \ the \ car = 16 \ m/s}`

Given:

Initial speed (u) = 10 m/s

Acceleration (a) = 2 m/s²

Time taken (t) = 3s

To Find:

Final speed (v) of the car

Step-by-step explanation:

From equation of motion we have:

`\boxed{ \bold{v = u + at}}`

By substituting value of u, a & t in the equation we get:

`\sf \implies v = 10 + 2* 3 \\ \\ \sf \implies v = 10 + 6 \\ \\ \sf \implies v = 16 \: m {s}^( - 1)`

`\therefore`

Final speed (v) of the car = 16 m/s
