Drag Race Calculator Quarter Mile
Fill in the information and then click on button.
Enter Distance Here : (Feet)
Quarter Mile = 1320 Feet
Enter Time Here in Seconds : (Seconds):
Time = 10 Seconds
Enter Weight of Car: (Lbs)
Average Fast Car = 3200 Lbs
Enter Friction Constant :
Average For Rubber on Asphalt = .7 => .7*3200 = 2240 Lbs
Enter Speed Acquired (mph) :
Speed = 162 mph
Acceleration :
A = (V2 - V1)/T Where V2 = Ft/Sec and T = Seconds
Grip of Tires :(Lbs)
Thrust Needed for Speed Aquired :
Pounds of Force = Thrust => F = m*a
Speed of Gravity for 1320 feet = V2 = 5.454*(sq-rt(1320)) = 198.1537 mph
Enter-01:
Distance Here:(Feet)Quarter Mile = 1320 Feet
Enter-02:
Time Here in Seconds:(Seconds)Time = 5 Seconds
Enter-03:
Weight of Car = 3200 lbs
Enter-04:
Enter Friction Constant = .07 = Rolling Friction of Car = .07*3200 = 224 lbs
Answer-01:
V2 = (2*X)/T = ft/sec
Answer-02:
a = V2/T = ft/sec/sec
Answer-03:
MPH = V2*(60/88) = Miles/Hour
Answer-04:
Mass of Car = 3200/32 = 100 slugs
Answer-05:
Rolling Friction of Car = .07*3200 = 224 lbs
Answer-06:
Total Thrust Needed = F = m*a + Frictional Force = 100*a + 224 = 10784 lbs
Zero to 60 mph in 6 seconds:
Enter-01:
MPH = 60 miles/hour
Enter-02:
Time Here in Seconds: Time = 6 Seconds
Answer-01:
Convert to ft/sec 60 mph = 88 ft/sec
Answer-02:
a = (V2 - V1)/T
Answer-03:
X = (V2*V2)/(2*a) = Distance Traveled
Answer-04:
V2*V2 = 2*a*1320 = Quarter Mile
Answer-05:
V2 = SqRt(2*a*1320) = Speed (ft/sec) at Quarter Mile
Answer-06:
V2 = Speed at Quarter Mile = MPH
Answer-07:
T = V2/a = Time (Seconds) at a Quarter Mile
