Please help me! I don't understand how to do this! 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?

Part 2: What is the net force acting on the shopping cart during that time? You will need your answer from the previous part.

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

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
