Question

find the net force required to give an automobile of mass 1800kg an acceleration of 4.75m/s

Answer 1

Answer:

Mass of automobile=1800Kg

Acceleration produced=4.75 m/a

According to second law of motion

F=ma

= 1800 Kg×4.75 m/a

=8550 N

So,net force acting on automobile us 8550 N.

Answer 2

Given:-

• Mass of object = 1800kg
• Acceleration = 4.75m/s

To find:-

• Force required to give acceleration

Solution:-

We know that Force is written as product of mass and acceleration.

$\large\rightarrow F=M\times A$

$\large\rightarrow F=1800\times 4.75$

$\large\rightarrow F=8550N$

Hence the required force is 8550N

Note:-

• A- acceleration
• F- force
• M- mass
