Homework Statement
A speed skater moving across frictionless ice at 8.7 m/s hits a 5.6 m -wide patch of rough ice. She slows steadily, then continues on at 6.0 m/s.
What is her acceleration on the rough ice?
Homework Equations
(v1-v0)/t
The Attempt at a Solution
So I've attempted to determine the amount of time it takes her to get across the ice by dividing 5.6 m/s to 8.7 m/s getting .64 m/s to cross the rough patch. So the equation I tried was this: (6.0-8.7)/.64 = -7.59 which isn't correct. I'm in need of some help...
