SUMMARY

The discussion focuses on calculating the acceleration of an object moving with uniform acceleration, given its initial velocity of 11.0 cm/s and a displacement from 2.91 cm to -5.00 cm over a time interval of 2.75 seconds. The calculated acceleration is -10.1 cm/s². Participants suggest using the SUVAT equations of motion, specifically the relationship between displacement, time, initial velocity, and acceleration to derive the solution.

No idea how to do this.

An object moving with uniform acceleration has a velocity of 11.0 cm/s in the positive x-direction when its x-coordinate is 2.91 cm. If its x-coordinate 2.75 s later is −5.00 cm, what is its acceleration?

The answer is -10.1 cm/s squared but I don't know how to get to the answer. Any help would be great. Thanks.

As you know velocity=Δdisplacement/Δtime.
What do you know about constant acceleration definition?
 
Perhaps look at one of the SUVAT equation of motion.

You know the displacement s, the time t and the initial velocity v.

I'll let you decide which equation you need to solve for "a".
