Thank you We sneak and here's your shmoop too sure

00:05

brought to you by basketball tryouts We were all set

00:08

to make the best ball team until they told us

00:10

our springy shoes were their words against the rules All

00:14

right What is the restoring force on a spring with

00:17

a spring constant of five newtons per meter that has

00:19

stretched toe four meters and hear the potential answers dinner

00:24

All right well the answer this question We need to

00:26

be familiar with hooks law which is stay away from

00:29

hungry crocodiles Wait That's captain hook's a lot of different

00:32

things Books lot tells us that the restoring force of

00:35

a spring is equal to its constant times its displacement

00:40

or how much it stretched Any equation k is the

00:43

spring constant and x is displacement Since the spring constant

00:48

is reacting against a force hey is expressed as a

00:51

negative number Well luckily for us his question is crazy

00:54

generous and gives us both of the numbers we need

00:57

to solve it So in this case the force equals

00:59

negative five newtons per meter times four meters giving us

01:02

an answer of negative twenty newtons making the correct answer

01:05

Option d you can also use hooks a lot of

01:08

fine the restoring force of a compressed spring The formula

01:11

would be the same but since the spring is compressed

01:15

the displacement would be expressed as a negative number And

01:18

since both the spring constant and the displacement would be

01:21

negative the resulting force would be a positive number So

01:25

with this knowledge hopefully we can perfect are springy shoes

01:28

because well it turns out we're still having some issues
