Use
v1^2-v0^2=2(a)(Δx)
or
Δx = (v1^2-v0^2)/(2a)
a=acceleration,
v0=initial velocity
v1=final velocity
Do not forget to convert km/h to m/s to get your answer in metres.
A certain car is capable of accelerating at a
uniform rate of 0.83 m/s2
.
What is the magnitude of the car’s displacement
as it accelerates uniformly from a speed
of 80 km/h to one of 92 km/h?
Answer in units of m.
