Here is the third direction through the same equation. A 6.0 N net force gives a drone an acceleration of 1.5 m/s². What is the drone's mass?
One more rearrangement completes the set.
Start from a = F_net/m.
Multiply both sides by m: m × a = F_net.
Divide both sides by a: m = F_net/a.
With F_net in newtons and a in m/s², the mass comes out in kilograms.
You now own all three directions through a = F_net/m. From here, the work is reading which quantity a question wants.
A 6.0 N net force gives a drone an acceleration of 1.5 m/s². Calculate the drone's mass.
Write down the values in the question:
F_net = 6.0 N
a = 1.5 m/s²
m = ?
Write down the equation:
a = F_net/m
Make m the subject:
m = F_net/a
Substitute in the values:
m = 6.0 ÷ 1.5
Simplify:
m = 4.0 kg
The drone's mass is 4.0 kg.
The net force on a loaded canoe is 150 N, and it accelerates at 2.0 m/s². Calculate its total mass.
Write down the values in the question:
F_net = 150 N
a = 2.0 m/s²
m = ?
Write down the equation:
a = F_net/m
Make m the subject:
m = F_net/a
Substitute in the values:
m = 150 ÷ 2.0
Simplify:
m = 75 kg
The loaded canoe's total mass is 75 kg.
