Question

I really need help on questions 4&5 I’m really lost. My teacher is never there to teach the class anything and never helps :(

Answer 1

Q. 4:

Recall Newton's second law of motion,

$F=m\cdot a$

Where F is the force, m is the mass, and a is the acceleration of the object.

Re-writing the above equation

$m=\frac{F}{a}$

As you can see, if force is held constant then the mass of the object is inversely proportional to the acceleration of the object.

Quadrupling the mass means 4 times the mass
