If 525 N of force is applied to a 4.5
kg mass, how fast will it accelerate?

121.11m/s²

Explanation:

Given parameters:

Force   = 525N

Mass = 4.5kg

Unknown:

Acceleration  = ?

Solution:

From Newton's second law of motion, we can find the solution to this problem. Using the expression below:

       F  =  m x a

F is the force

m is the mass

a is the acceleration

      So'

              525  = 4.5 x acceleration

            Acceleration = 121.11m/s²
