Answer 1

Answer:

150meitor is correct answer

Answer 2

SOLUTION

GIVEN

A car starts from 10 m/s and picks up a velocity of 20 m/s in 10 seconds.

TO DETERMINE

The distance covered during this period

EVALUATION

Here it is given that a car starts from 10 m/s and picks up a velocity of 20 m/s in 10 seconds.

Thus we have

Initial velocity = u = 10 m/s

Final velocity = v = 20 m/s

Time = t = 10 seconds

a = Acceleration = ?

Now we get

$\sf{v = u + at}$

$\sf{ \implies \: 20 = 10 + 10a}$

$\sf{ \implies \: 10a = 10}$

$\sf{ \implies \: a = 1}$

Acceleration = 1 m/s²

Let s = The distance covered

$\sf{ {v}^{2} = {u}^{2} + 2as}$

$\sf{ \implies \: {20}^{2} = {10}^{2} + 2 \times 1 \times s}$

$\sf{ \implies \: 400 = 100 + 2 s}$

$\sf{ \implies \: 2 s = 300}$

$\sf{ \implies \: s = 150}$

The distance covered = 150 m
