## Homework Statement

a 1kg block sliding a frozen surfaces collideds w/a horizontal spring w/a force constant of 2N/m. The block compresses the spring 4m fr. its rest position.

a.how long does it take to fully colmpress the spring?b. what wa sthe speed of the block at the instant of the collision?c. when the springs is compressed 1.7m, how much force is the block on it?

## Homework Equations

k=force constant A=4m x=1.7m

T=2pi(sqroot (m/k)

vmax=(2piA)/(T)

F/x=k

## The Attempt at a Solution

I used the T eq. to find the answr for a. which is 4.44s

Then I took T and plugged in for vmax eq. and have the speed as 5.66m/s

for c. I used the f/x=k equation and came up with F=3.4N

is this the way I'm suppose to do it, it somehow seems too easy to be true? =x
