Question

A potato launcher uses a spring that can apply a force of 20N to potato’s. He launches a 100 gram potato, what is the acceleration? Then he launched a 150 gram potato what is the acceleration? He then launched a 200 gram potato What is the acceleration?

Answer 1

Answer:

200 m s^-2.

133.33 ms^-2.

100 m s^-2.

Step-by-step explanation:

Use Newton's Second Law of motion:

Force = mass * acceleration

The force is in Newtons so the mass must be in kilograms#

100 g = 0.1 kg. So:

20 = 0.1 * a

a = 20/ 0.1 = 200 m s^-2.

We calculate the acceleration for  the 150g and 200g potato in the same way.
