Question

When a constant force is applied to an object, the acceleration of the object varies inversely with its mass. When a certain constant force acts upon an object with mass 34 kg

, the acceleration of the object is 2 /ms2

. When the same force acts upon another object, its acceleration is 17 /ms2

. What is the mass of this object?

Answer 1

Newton's second law: F = MA

An object of 34kg being accelerated by 2m/s²:

F = (34)(2) = 68N

When this force acts on an object, accelerating it at 17m/s²:

68 = M(17)

M = 68/17kg
