Question

An object with a mass of 15 kg has an acceleration of 4 m/s2, what is the resultant force

Answer 1

• Mass=15kg
• Acceleration=4m/s^2

Using Newton second law

`\\ \sf \longmapsto Force=Mass* Acceleration`

`\\ \sf \longmapsto Force=15(4)`

`\\ \sf \longmapsto Force=60N`

Answer 2

F = m • a

F = (15 kg) • (4 m/s^2)

F = 60 Newtons

NOTE:

That's NOT a "resultant force".

That's the force you have to EXERT on 15 kg to MAKE it accelerate at 4 m/s^2 .
