Question

What is the net force required to give an automobile of mass 1600 kg an acceleration of 4.5m/s2?

Answer 1

Answer : Net force is 7200 N.

Explanation :

It is given that,

Mass of an automobile, m = 1600 kg

Acceleration produced, $a=4.5\ m/s^2$

The second law of motion gives the relationship between the force acting and the acceleration as :

F = ma

$F_{net}=1600\ kg\times 4.5\ m/s^2$

$F_{net}=7200\ N$

So, the net force acting on the automobile is 7200 N.

Hence, this is the required solution.

Answer 2

Answer:

Net force is 7200 N

Explanation:

Mass = 1600 kg

Acceleration = 4.5 m/s^2

Net force = Mass * Acceleration

                = 1600 * 4.5

                = 1600 * 45 / 10

                = 7200 N
