Vf^2=Vi^2+2ad
0=39^2+2(NetForce/mass)*1270
solve for net force.
note that masscar= 8036/g
The parachute on a race car that weighs
8036 N opens at the end of a quarter-mile
run when the car is traveling 39 m/s.
The acceleration of gravity is 9.81 m/s2 .
What net retarding force must be supplied
by the parachute to stop the car in a distance of 1270 m?
Answer in units of N.
