I. Program Making. (60 pts.)

Create an application that shows how to calculate the compound interest of a saving.

Prerequisites:
• Dialog Boxes
• Group Box

When you deposit money in a savings account, your money earns interest that is calculated every month or quarter, etc. Because this is not money you need right away, the amount accrued can be reinvested, thus boosting your interest so the next calculation would be based on the original amount plus the new added value. This is the basis of compound interest.

The compound interest can be calculated monthly or quarterly, etc based on the original amount you deposited, the interest rate, and the period you and the institution agreed upon.

This application uses a dialog box equipped with the necessary controls used to perform the type or related calculated. The formula we will use to perform the calculations is as follows:

a

Design the form as follows:

b

II. Problem Solving: (Show your solutions)

1. A truck starts from rest and gains a velocity of 20 km/hr in 8 seconds while moving on a straight road. What is the magnitude of acceleration of the truck?
2. A mountain climbing expedition establishes a base camp and two intermediate camps, A and B. Camp A is 11,200 m east of and 3,200 m above base camp. Camp B is 8,400 m east of and 1,700 m higher than Camp A. Determine the displacement between base camp and Camp B.
3. An ambitious hiker walks 25 km west and then 35 km south in a day. Find the magnitude and direction of the hiker’s resultant displacement (relative to due west).
4. I went for a walk the other day. I went four avenues east (0.80 miles), then twenty-four streets south (1.20 miles), then one avenue west (0.20 miles), and finally eight streets north (0.40 miles).
a. What distance did I travel?
b. What’s my resultant displacement (magnitude and direction relative to due east)?
5. While Dexter is on a camping trip with his boy scout troop, the scout leader gives each boy a compass and a map. Dexter’s map contains several sets of directions. For the two sets below, draw and label the resultant (R). Then use the Pythagorean theorem to determine the magnitude of the resultant displacement for each set of two directions.
a. Dexter walked 50 meters at a direction of 225° and then walked 20 meters at a direction of 315°.

b. Dexter walked 60 meters at a direction of 135° and then walked 20 meters at a
direction of 45°.
