Question

A car moving with a (sqcjqydfdh) of 10 ms gains a velocity of 30 ms after travelling a distance of 4kn then acceleration is a) 0.1 ms? b) 0.45 ms c) 0.25 ms d) 0.35 ​

Answer 1

Answer:

Velocity (v) = 30

Distance = 4km

Acceleration = 0.1ms

Answer 2

Answer:

ACCELERATION = 0.1 ms-2

Explanation:

Given,

u = 10 m/s

v = 30 m/s

s = 4 km = 4000 m

a = ?

The equation of motion :

$v^{2} - u^{2} = 2as$

900 - 100 = 2 * a * 4000

800 = 8000 a

a = 800 / 8000

a = 1/10 ms-2

a = 0.1 ms-2
