These are all very similar. Get those three equations in your head. You will see them all.
For a standard production car, the highest road-tested acceleration ever reported occured in 1993, when a Ford RS200 Evolution went from zero to 26.8 m/s (60 mi/h) in 3.275 s. Find the magnitude of the car's acceleration.
displayed by
m/s2
Repeat, for another car which goes from zero to 60 mi/h in 4.940 s.
calculated in m/s2
trying to understand all the variable involved. thanks for any help you can give here. appreciate it.
[SUVAT! . Motion caused by..., or where acceleration is constant.]
Evolution went from zero to 26.8 m/s (60 mi/h) in 3.275 s. Find the magnitude of the car's acceleration, displayed by m/s^2
V final, Vf = Vo +at -----------(i)
Given:
Vo = 0
Vf = 26.8 m/sec
t = 3.275 sec
Find a.
26.8 = 0 +a(3.275)
a = 26.8 /3.275 = 8.183 m/sec/sec -------------answer.
Repeat, for another car which goes from zero to 60 mi/h in 4.940 s.
calculated in m/s2
Vo = 0
Vf = 60mi/hr = 26.8m/sec
t = 4.94 sec
Vf = Vo +at
26.8 = 0 +a(4.94)
a = 26.8 /4.94 = 5.425 m/sec/sec --------------answer.
