Givens:

vi= 0 m/s

vf= 177 mph

d= ¼ mile

t= 7.99 sec

m= 3,284 lbs

Conversions: = 402.4 meters

[ATTACH=CONFIG]83[/ATTACH]= 402.4 meters

[ATTACH=CONFIG]84[/ATTACH] = 79.1 m/s

[ATTACH=CONFIG]85[/ATTACH]= 1,489.6 kg

Kinematics:

vi= 0

vf= 79.1 m/s

a= ?

d= 402.4 m

t= 7.99 s

[ATTACH=CONFIG]86[/ATTACH]

Force: Fn=ma => Fn= (1,489.6kg)(9.9 m/s^2) => Fn= 14,747 N

Work: W= Fnd => W= (14,747 N)(402.4 m) => W= 5,934,192.8 j

Power:

Kinetic energy:

KE= 1/2mv^2 => KE= ½(1,489.6 kg)(79.1^2 m/s) => KE= 4,660,072.88 j

The role of friction in this video: the friction from the rubber of the tires spinning on the asphalt creates heat and traction hich creats more grip to help enhance performance.
