Traveling at a speed of 17.3 m/s, the driver of an automobile suddenly locks the wheels by slamming on the brakes. The coefficient of kinetic friction between the tires and the road is 0.600. What is the speed of the automobile after 2.30 s have elapsed? Ignore the effects of air resistance.

Spare us man! ..............Its not an Examination Hall...Questions need to be easy but twisting in nature and not involving complicated formulae and calculations!

You should have seen enough force/mass/acceleration problems with friction to be able to figure this out. This one is easier than the others. Just remember Fr = µs*Fn, F=m*a, and v=a*t.

You should ask my oldest son, Chad could figure this no problem, he excelled in calculus! Now he's working in Aerospace and he's 22 years old!
Me? Ha ha he he he, when it comes to Math! I'm sure you'll find someone to answer that, if it's possible...Is it?
