A 2 kg car accelerated from 10 m's to 20 m/s using a force of 3000N. How quickly did it
elena-14-01-66 [18.8K]

Answer:

the car accelerates in

\frac{1}{150}  \: or \: 0.006 \: second

Explanation:

here's the solution : -

we know,

=》

force = mass   \times acceleration

=》

acceleration =  \frac{force}{mass}

=》

a  =  \frac{3000}{2}

=》

a = 1500

so, acceleration = 1500 m/s^2

now,

=》

a =  \frac{v - u}{t}

here, a = acceleration, v = final velocity,

u = initial velocity, t = time taken.

So,

=》

1500 =  \frac{20 - 10}{t}

=》

1500 =  \frac{10}{t}

=》

t =  \frac{10}{1500}

=》

t = 0.006 \: sec
