A 1.5 N stone is thrown vertically upward with an
initial speed of 15 m/s . Calculate
a. P.E at the maximum height
b. K.E at the instant it will strike the ground
c. P.E after 1 s
d. K.E after 1 s
1.You play a game with two six-sided dice. If you roll a sum of 4 or 7, you win P 400. If you roll a sum of 10,you win 200. However, you lose 300 for anything else. If you continue to play the game, how much do you expect to win or lose in the game?
CALCULATE THE MOLALITY OF A SOLUTION CONTAINING 10.8 G OF ETHYLENE GLYCOL, C2H602, IN 360 G OF WATER.
DETERMINE THE MOLARITY OF A SOLUTION CONTAINING 2.40 G OF SODIUM CHLORIDE IN 40.0 ML OF SOLUTION.
CALCULATE THE MOLE FRACTION OF EACH COMPONENT OF A SOLUTION CONTAINING 65 G OF ETHANOL IN 350 G OF WATER.
Find the charge and current at time t in the circuit, at R = 40 ohms, L = IH, C = 16X10^-4 F
E(t) = 100cos(10)t, initial charge and current are both zero.
The XYZ Telephone Company’s charges file, contains records for each call made by its subscribers during a month. Each record on a file contains the subscriber’s name and phone number, the phone number called, the distance from Shah Alam of the number called (in kilometres) and duration of the call in seconds.
Design an algorithm that will read the Tidy Phones charges file and produce a telephone charges report, as follows:
The cost of each call is calculated based on table 1.

Write C++ complete programs for the above problem. You program must use control structure and user defined function.
Examine the markets and/or industries in your area.
Describe each one, and categorize it in terms of being pure competition,
pure monopoly, monopolistic competition, or oligopoly.
Which type of market is most common? How do you explain this?
A spring with mass of 2 kg has natural length of 0.5 m. A force of 25.6 N is required to maintain, it stretched to a length of 0.70 m. If the string is stretching to a length of 0.70 m and then released with initial velocity 0, find the position of mass at anytime t.

As a junior programmer, you are required to design and write a complete C++ program that asked the user to enter subscriber’s name and phone number, the phone number called, the distance from Shah Alam of the number called (in kilometers) and duration of the call-in seconds. The user also needs to enter types of call either Local or International call.
The cost of each call is calculated based on Table 1.

Your program should use the following:
1. Appropriate Control Structure
2. User Defined Function
3. Sets the decimal precision to be used to format floating-point values on output operations. (2 decimal places)
4. Set background and text colour for output
