Question

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

Answer 1

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 2

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
