A force of 8,480 N is applied to a cart to decelerate it at a rate of 32.0 m/s2. What is the mass of the cart?
GuDViN [60]
The realtionship between force in Newtons, mass in kilograms and acceleration in metres per second squared is described by Newton's second law of motion which is Force = mass times acceleration, or F=ma.  You need to know the mass, so rearrange the formula to solve for m, giving m=F/a
In your example, the mass is therefore  8480 divided by 32, which is equal to 265kg.
