The Bugatti Veyron is able to accelerate at 12.3 m/s2. The Ford Fusion is able to accelerate at 4.2 m/s2. Which of the following statements best calculates the
additional time required for the Ford Fusion to reach 1 km from rest if both are given
maximum accelerations and justifies the mathematical routine?
atasan

what was the acceleration of the 2 kg cart?

⇒ 16.0 cm/s2

what was the acceleration of the 4 kg cart?

⇒ 8.1 cm/s2

what was the acceleration of the 6 kg cart?

⇒ 5.3 cm/s2

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
