17) Apply this equation to calculate the acceleration of the car:

a = Δv/Δt

a = acceleration, Δv = change in velocity, Δt = elapsed time

Given values:

Δv = 80m/s - 110m/s = -30m/s, Δt = 20s

Plug in and solve for a:

a = -30/20

a = -1.5m/s²

18) Rearrange the acceleration equation:

Δv = aΔt

Given values:

Δv = 40m/s, 5m/s²

Plug in and solve for Δt:

40 = 5Δt

Δt = 8s
