Homework Help: physics please help!

Posted by Gray on Wednesday, September 10, 2008 at 12:08am.

A car driving along a straight road increases its velocity from 2.8 m/s to 9.7 m/s in 3 seconds. Calculate its acceleration in m/s^2

A skier in the Giant Slalom will accelerate at a constant 5.0 m/s^2 If she starts from rest, how fast is she going after 5 seconds?

A skier at the top of a run will accelerate at a constant 4.0 ft/s^2 If she starts from rest, how far does she travel in 5 seconds?

Please help me with these 3 questions. I am very confused. Thank you.
