Your shopping cart has a mass of 65 kilograms. in order to accelerate the shopping cart down an aisle at 0.3m/sec^2 , what force would you need to use or apply to the cart

The equation you would use here is F=ma, where F is the force in Newtons, m is the mass in kilograms (must be in kilograms in order for the units to match on both sides), and a is acceleration in meters per second squared. Therefore, you do: 65kg x .3m/s^2= FF. That'll give you the answer.
