Question

A potato launcher uses a spring that can apply a force of 20N to potatoes. A sstudents lauched a 100g potato, a 150g potato, and a 200g potato with the launcher. Which had the greatest acceleration?

Expert Solution

Step 1

Explanation:

Simply use F = ma for net force F acting on mass m causing acceleration of a,

Given,

F = 20N,

m = (100 / 1000) = 0.1Kg

So, a = F / m

=20 / 0.1

=200 ms^−2

Again,

m = (150/ 1000) = 0.15Kg

So, a = F / m

=20 / 0.15

=133.3333 ms^−2

Again,

m = (200 / 1000) = 0.2Kg

So, a = F / m

=20 / 0.2

=100 ms^−2

Finally we can say that The 100 gram potato will have a higher acceleration. Less mass = more acceleration.
