A skier needs to apply a force of 132 N to accelerate at a rate of 2 m/s². What formula do we use to find the mass of the skier?

F = MA

M = F / A

A = F / M

• 132 ÷ 2

• 2 ÷ 132

• 132 x 2

A 5 kg block is pulled across a table by a net force of 32 N. What formula do we use to find the acceleration of the block?

F = MA

M = F / A

A = F / M

• 32 ÷ 5

• 5 ÷ 32

• 32 x 5
