Question

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

Answer 1

Answer:

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

Given:

Initial speed (u) = 10 m/s

Acceleration (a) = 2 m/s²

Time taken (t) = 3s

To Find:

Final speed (v) of the car

Explanation:

From equation of motion we have:

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

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

$\sf \implies v = 10 + 2\times 3 \\ \\ \sf \implies v = 10 + 6 \\ \\ \sf \implies v = 16 \: m {s}^{ - 1}$

$\therefore$

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