A car can decelerate at -400 ms2 without skidding when, Ask an Expert

Academics

A car can decelerate at -4.00 m/s2 without skidding when stopping on a level road. What would be the magnitude of its deceleration if the road were inclined at 15° uphill? (Hint: Do the problem when the car is on a level road to determine the coefficient of friction, the do the problem again when the car is on an inclined road using that coefficient of friction.)
