## Homework Statement

A sportscar, Fiasco I, can accelerate uniformly to 76 m/s in 30 s. Its maximum braking rate cannot exceed 0.60g. What is the minimum time required to go 1250 m, assuming the car begins and ends at rest?

## Homework Equations

a = v/t

v = d/t = [tex]\Delta[/tex]r/t

v

_{avg}= (v

_{i}+ v

_{f})/2 [when a is constant]

## The Attempt at a Solution

accelrate1 = (76m/s) / 30s = 2.53 m/s^2

accelrate2 = - (0.60)g = - (0.6)(9.8N/kg) = -5.88N/kg = -5.88 m/s^2

**r**

_{i}= <0,0,0>m

**r**

_{f}= <1250,0,0>m

**v**

_{i}= <0,0,0>m/s

**v**

_{f}= <0,0,0>m/s

I tried breaking it up into two parts, the first being the acceleration and the second being the deceleration, but I cannot seem to get the correct answer.
