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

Net force is calculated using the equation

F=ma

where m is mass and a is acceleration.

So, F = (1600kg) (4.5m/s^2)

= 7200N

Answer: 7200 N

Identify the given information.

m = 1600 kg

a = 4.5 m/s²

Choose which formula you should use. In this case, you are finding the force.

f = ma, where m is the mass and a is the acceleration.

Substitute and solve.

f = (1600 kg) (4.5 m/s²)

f = 7200 N
