One end of a horizontal spring with force constant 76.0 N/m is attached to a vertical post. A 2.00-kg can of beans is attached to the other end. The spring is initially neither stretched nor compressed. A constant horizontal force of 51.0 N is then applied to the can, in the direction away from the post.

a) What is the speed of the can when the spring is stretched 0.400 m?

_____ m/s

b) At the instant the spring is stretched 0.400 m, what is the magnitude of the acceleration of the block?

_____ m/s^2

Thank you so much!

I need help on this project at school.

It's basically dropping an egg at 10ft or so and then hoping it doesn't crack and ruin our grade. ^_^

So I was wondering, what can we do so that the egg doesn't break?
