Question

3. Law of Acceleration: A 1400 kg car has an acceleration of 3.6 m/s. What is the net force applied by the engine?

Answer 1

In order to calculate the net force, use the Newton second law:

$F=m\cdot a$

where,

m: mass = 1400 kg

a: acceleration = 3.6 m/s^2

Replace the previous values of the parameters into the formula for F:

$F=(1400kg)(\frac{3.6m}{s^2})=5040N$

Hence, the net force applied by the engine is 5040N
