A 1,200 kg car is accelerated at 3.7 m/s2. What force was needed to produce this acceleration?
2 answers:
Answer:
A. 4,440 N
Explanation:
A Force applied on an object with mass 'm' can change its velocity in a unit time. This change is called acceleration.
If a force 'F' is applied on a body of mass 'm', it produces an acceleration 'a' in the body.
Force is give as :
F = ma
In our case,
m = 1200 kg a = 3.7 m/s²
F = 1200 x 3.7
F = 4440 kgm/s²
F = 4440 N
