Michael applies a 8 N rightward force to a 0.75 kg book to accelerate it across a table top. The coefficient of friction between the book and the tabletop is 0.610. Determine the acceleration of the book.
Determine the accelerations that result when a 20 N net force is applied to a 5 kg object and then to an 8 kg object.
A force of P N acting on a body of 5kg traveling with a velocity of 5ms-1 increases it velocity to 10ms-1. if the force acts in the direction of motion for a period of 5s, what is the value of P?

Do Exercise 6.4 from your textbook using recursion and the is_divisible function from section 6.4.
A monopolist with the cost function c=½q² faces demand curve q=12-p
A. What will be his equilibrium price and quantity ?
B. If the some reason the firm behaves as if it were in a perfectly competitive idustry, what will equilibrium price and quantity ?
c. How much money will the firm require to forgo monopoly profits and behave competitively instead ?
What will be the electric field experienced by a test charge if q = 7.03 x 10^-6 C from a source charge q = 12 x 10^-6 C in a vacuum when the test charge is placed 0.25 m away from the other charge?
The numbers 5, 10, 15, and 20 are written on slips of paper, which are then placed in a hat. Two slips are randomly selected with replacement. Find the mean of the samples where the first is smaller than the second.
