State Newton's Second and Third Laws of Motion, both in equation form and in words. Be specific with your definitions (There's no need to give examples. State the grown-up version, not the kiddie version) Question 2. Two forces act upon a car of mass M as shown in the figure above. Find an expression for the acceleration, a, in terms of T, F. and M (Hint: F is not the net force, just an applied force). What would happen to the acceleration if the mass is doubled? Question 3. An object of mass M is in free-fall (the only force on the object is its own weight). Make a force diagram for this case. Use Newton's Second Law to calculate the acceleration of the object.

Step 1

Equation for net force acting on the car from Newton’s second law is,

Step 2

a  is the acceleration of car.

There are two forces, T and F. These forces are in opposite direction. The arrow representing T is smaller than F. It means that F has greater magnitude than T.

Equation for Fnet is,

Step 3

Substitute the above equation ...
