Question

A car moving with a velocity of 10ms,gain a velocity of 30ms after traveling a distance of 4km then acceleration is

Answer 1

Answer:

Given:

Initial velocity = 10 m/s

Final Velocity = 30 m/s

Distance covered = 4 km

To find:

Acceleration of the object

Conversion:

Convert the distance from km to metres ;

4 km = 4000 m

Calculation:

Let final Velocity be "v" , initial Velocity be "u" , acceleration be "a" and distance be "s"

v² = u² + 2as

=> 30² = 10² + 2 × a × 4000

=> 900 = 100 + 8000a

=> 8000a = 800

=> a = 0.1 m/s²

So acceleration of the body is 0.1 m/s²

Answer 2

Answer:

0.1 m/s^2

Explanation:

The acceleration is above
