I've been trying to figure this problem out for a few hours now. Please, if you have helpful hints, help me out!(adsbygoogle = window.adsbygoogle || []).push({});

You can see the problem here on page 7, the problem about the toy cricket: http://www.physics.princeton.edu/~mcdonald/examples/ph101_2006/learning_guide_ph101_2006.pdf

--------------------------------------------------------------------------------------

A toy cricket is stuck to the floor with a suction cup which after a few moments releases to allow a spring to propel the cricket upward. The expanding spring accelerates the cricket over a distance of 0.01 m to point A, after which the toy travels freely to a maximum height of 1.00 m above the ground (point B).

What is the net acceleration during the time the spring expands? Assume uniform acceleration.

The answer is 970 m/s^2.

I just do not know where to start. I assume we use x = (1/2)(acceleration)(t^2) but don't know enough of the variables to plug and chug.
