Problem

A top-fuel dragster starts from rest and accelerates at +17.0

\frac{m}{s²}

for 402 m. A parachute then opens behind the dragster to slow it down with an acceleration of -6.10

\frac{m}{s²}

. How fast is the dragster moving 350 m after the parachute opens? a. 86.9

\frac{m}{s}

b. 88.9

\frac{m}{s}

c. 96.9

\frac{m}{s}

d. 98.9

\frac{m}{s}

e. 102.9

\frac{m}{s}
