 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
