Newton’s 2nd Law: F=ma. If you push a shopping cart with 130 N of force, and it accelerates at 3 m/s², what is the mass of the cart?

43.3kg

Explanation:

Given parameters:

Force  = 130N

Acceleration  = 3m/s²

Unknown:

Mass of cart  = ?

Solution:

From Newton's second law of motion:

        F = m x a

F is the force on the body

m is the mass

a is the acceleration

 So;

          m  =   =   = 43.3kg

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
