Asked Oct 28, 2019

A 6.6 kg object undergoes an acceleration of 4.2 m/s2.

What is the magnitude of the resultant force acting on it? 

 If this same force is applied to a 4.0 kg object, what acceleration is produced? 


Expert Answer

Step 1

From Newton’s second law of motion.

Е. - та
=(6.6 kg) (4.2 m/s2)
27.7 N

Е. - та net =(6.6 kg) (4.2 m/s2) 27.7 N

Step 2

Therefore, the magnitude of the force acting on the object of mass 6.6 kg is 27.7 N.

Step 3

Now, if the same force is applied on another object of mass 4.0 kg. Then consider that the accelerat...

= m'a'
27.7 N= (4.0 kg)a
27.7 N
4.0 kg
=6.92 m/s

= m'a' net 27.7 N= (4.0 kg)a 27.7 N 4.0 kg =6.92 m/s
