Question

What amount of unbalanced force will cause a 45 kg object to accelerate at a rate of 3.0 m/s2

Answer 1

• Mass=m=45kg
• Acceleration=a=3m/s^2

Force=F

Apply Newton's second law

`\\ \tt\longmapsto F=ma`

`\\ \tt\longmapsto F=45(3)`

`\\ \tt\longmapsto F=135N`

Answer 2

135N will cause a 45 kg object to accelerate at a rate of 3.0 m/s2

Step-by-step explanation:

Force = mass * acceleration

Force = 45 kg * 3 m/s2

Force = 135N
