Answer 1

★Answer :

$\boxed {\boxed {\sf 50,000 \ Newtons }}$

★Explanation:

Force can be found by multiplying the mass by the acceleration.

$\sf {F=m×a}$

→The mass of the car is 5,000 kilograms and it's acceleration is 10 meters per square second.

$\sf m= 5,000 \ kg$

$\sf {a= 10 \ m/s^2}$

•Substitute the values into the formula.

$\sf {F= 5,000 \ kg × 10 \ m/s^2}$

❄️Multiply :

$\sf {F= 50,000 \ kg×m/s^2}$

1 kilogram meter per square second is equal to 1 Newton.

So, our answer of 50,000 kg×m/s² is equal to 50,000 Newtons

$\sf F= 50,000 \ N$

A net force of 50,000 Newtons is required to accelerate a 5,000 kilogram car at 10 meters per square second.

Answer 2

Given :-

Acceleration = 10m/s²

Mass = 5000 kg

To find :-

Net force = ??

Solution :-

Using Newton's second law :

Force = Mass x acceleration

$\sf\red{↠}$F = m x a

$\sf\red{↠}$F = 5000 x 10

$\sf\red{↠}$F = 50,000 N

$\underline{\green{\sf{ by \ 10m/s ² \ is \ 50,000 N }}}$
