Acceleration, Force & Mass

[tex]_____________________________________[/tex]

1. A net force of 15N is acting an object with a mass of 10kg what is the acceleration the objective

Acceleration

Given:

• Force - 15 N
• Mass - 10 kg

Answer & Solution:

• a = f ÷ m
• a = 15 N ÷ 10 kg
• a = 15 kg.m/s² ÷ 10 kg
• a = 1.5 m/s²

2.A horse is pulling a wagon with a mass of 15kg how much force is needed by the horse is order to accelerate at 0.5 m/5²

Force

Given:

• Mass - 15 kg
• Acceleration - 0.5 m/s²

Answer & Solution:

• F = ma
• F = (15 kg)(0.5 m/s²)
• F = 7.5 N

3. what is the mass of a truck if it produces a net force of 12000N force (f) while acceleration at a rate of 5.m/5²

Mass

Given:

• Force - 12 000 N
• Acceleration - 5 m/s²

Answer & Solution:

• M = f ÷ a
• M = 12 000 N ÷ 5 m/s²
• M = 12 000 kg.m/s² ÷ 5 m/s²
• M = 2 400 kg
