Answer:
2.55 m/sec^2
Explanation:
Part 1: A 6 kg shopping cart goes from a velocity of 0.9 m/s to a velocity of 6 m/s over the course of 2.0 seconds. What is the cart's acceleration?
The cart increases it's velocity by 5.1 m/sec. Divide by the 2 seconds it took to make that change:
(5.1 m/sec)/(2 sec) = 2.55 m/sec^2
Part 2: What is the net force acting on the shopping cart during that time? You will need your answer from the previous part.
F = m*a
F = (6kg)*(2.55 m/sec^2)
F = 15.3 kg*m/sec^2
F = 15.3 Newtons
