F=ma Hard

A skier needs to apply a force of 132 N to accelerate at a rate of 2 m/s². What is the mass of the skier? To solve this problem you must do - 

• 132 ÷ 2

• 2 ÷ 132

• 132 x 2

To calculate m

• m = Force × a

• m = Force ÷ a

• m = Force + a

• m = a ÷ Force

Why does a car accelerate faster with just the driver, compared to driver + 3 passengers?

• Car and driver has less mass than car, driver + 3 passengers

• Car and driver has more mass than car, driver + 3 passengers

• Car has less friction (drag)

• Car is accelerating faster
