A car traveling at 10 m/s speeds up to 20 m/s in 3 seconds. determine the acceleration of the car

Answer: 3.33m/s²

Explanation:

Acceleration = rate of change in velocity with time

Acceleration = change in velocity / time

Initial velocity (u) = 10 m/s

Final velocity (v) = 20m/s

time (t) = 3s

a = V - U / t

a = (20 - 10) / 3

a = 10 / 3 = 3.33m/s²

66m/s

Explanation:

because 10 meters/per second is going to be 22 mph/35 km, and 20m/s is 44 mph/70 km and in 3 seconds it would boost its mph/km (m/s) to 66 only because from 22 mph to 44 mph is 22 but 44/22 = 22, however you have top multiply that by 3 seconds which will coem out to 66 m/s, mph, km.
