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 4 kg, the acceleration of the object is 9 m/s². When the same force acts upon another object, its acceleration is 6 m/s². What is the mass of this
object?

Answer 1

Explanation:

a = k/m or ma = k

using 4 and 9 4* 9 = k = 36

then the equation becomes:

ma = 36

using a = 6

6 * m = 36 shows m = 6 kg
