Aracing car’s velocity is increased from 44 m/s to 66 m/s in 11 seconds. what is the acceleration? and what is the displacement?

Explanation:

Acceleration is defined as the change in velocity per unit of time

Acceleration (a) = ΔV/t

V = Velocity      t = time

ΔV = V₂ - V₁      t = 11s

V₁ = 44m/s

V₂ = 66m/s

ΔV = 66 - 44

     = 22m/s

Acceleration (a) = 22/11

                          = 2m/s²

Displacement (d): Displacement equals the original velocity multiplied by time plus one half the acceleration multiplied by the square of time.

d = v₀ + 1/2*at²

v₀ = 44m/s

a = 2m/s

t = 11s

d = 44 + 1/2*(2 x 11²)

  = 44 + 121

d = 165m

answer: b.

i tried it and took the test

if im wrong then we have different tests
