a car advertisement States that a certain car can accelerate from rest to70km/h in 7seconds find the car's average acceleration​

Acceleration is 2.78 m/s²

Explanation:

Since the car is from rest, initial velocity, u is zero.

from first newton's equation of motion:

v is final velocity

u is initial velocity

a is acceleration

t is time

70 km/h is (70 × 1000 ÷ 3600) m/s = 19.44 m/s

the journeys of marquette, joliet and la salle a) new france expand.
