Question

Given u = 2 m/s, s = 4 m/s , and assume acceleration as 9.8 m/s. so find the velocity of the object.​

Answer 1

Answer:

Given:-

u = 2 m/s

s = 4 m/s

a = 9.8 m/s (assuming)

where u means initial velocity

s mean distance/height and

a means acceleration due to gravity.

To find:-

Velocity of the object.

Solution:-

According to Newton's third law of motion,

$v {}^{2} - u {}^{2} = 2as \\ \\ {v}^{2} = 2 \times 9.8 \times 4 \\ \\ = 2.8 \: \frac{m}{s}$

Thus, velocity of the object is 2.8 m/s.

Answer 2

Answer:

2.8m/s will be the correct answer hope it helps you
