Question

What force would be required to accelerate a 1,100 kg car to 0.5 m/s2?

Answer 1

force = mass x exceleration 
1100 x 0.5 = 550

Answer 2

Answer: 550 N

Identify the given information. 
m = 1100 kg
a = 0.5 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 = (1100 kg)(0.5 m/s²)
f = 550 N
