A Number Game - About & How to play
About.
It's a number guessing game.
- The Player will have to guess a number that the Computer "hides" between a specified range of numbers. The Player is given four guesses.
- When the Player is able to guess, he will get to hide a number and the Computer will try to guess. The Computer is also given four tries.
- If the Computer unable to guess, the Player wins.
- He will earn a score of 1.
Consecutive winning will earn the Player the "winning streak".
The Player beats the game when he earns the winning streak of 5.
How to play.
To play, please download the .exe file and double-click it to start.
Remember. The point is to get the winning streak of 5.
Difficulty level may increase as your winning streak increases.
Use your four guesses wisely.
Good Luck.
P.S.
If you happen to earn the winning streak of 4 or above, please take a screen capture, upload it somewhere and send the link to this email or comment it below.

Kinematics Problem Solver - Example 4
Question: A boy dropped a ball from a cliff. Find the ratio of distance fallen in the first 4 seconds to the distance fallen in the first 2 seconds by the ball.
Answer:
From the question, we know that
- Initial velocity = 0 ms^-1.
- Time taken = 2 s and 4 s.
- Acceleration = 10 ms^-2.
- Displacement = ?
Neatly done.
Now, to find the ratio of the time taken of two different falls, we will have to run the program twice as such.
Distance fallen in the first 2 seconds of the ball is 20 m.
Distance fallen in the first 4 seconds of the ball is 80 m.
Let's put them in the ratio as the question wants us to do it.
distance fallen in the first 4 seconds : distance fallen in the first 2 seconds = 80:20 = 4:1.
The answer is 4:1.
Easy to use, isn't it?

Kinematics Problem Solver - Example 3
Question: A boy fired his M16 rifle to a tree. It is known that the muzzle velocity(velocity of the bullet) of his rifle is 975 m/s. The bullet is later found in the tree at a depth of 0.15m. Find the deceleration of the bullet.
(Air resistance is negligible.)
Answer:
From the question, we know that
- Initial velocity = 975 ms^-1.
- Final velocity = 0 ms^-1.
- Displacement = 0.15m.
- Deceleration = ?
Neat.
Now, let's enter these information into the program.
Fantastic.
-3.16875e+006 is -3.16875*10^6.
Small 'e' stands for exponent.
The problem is solved and
the answer is "Acceleration is -3.16875*10^6 ms^-2." which means that the deceleration of M16's bullet is 3.16875*10^6 ms^-2.
Well done.

Kinematics Problem Solver - Example 2
Question: A boy throws a ball vertically with a velocity of 2.0 m/s. What is the time taken for the ball to reach back to his hand?
Answer:
From the question, we know that
Neatly done.
Now, let's enter these information into the program as follow.
Answer:
From the question, we know that
- initial velocity = 2.0 m/s. (It was thrown with "a velocity of 2.0 m/s.")
- final velocity = -2.0 m/s. (It fell "back to his hand.")
- acceleration = -10 m/s^2. (Acceleration due to gravity, taking upwards as positive.)
- time = ?
Neatly done.
Now, let's enter these information into the program as follow.
Fabulous.
The program neatly solved for you. The answer is 0.4s.

Kinematics Problem Solver - Example 1
Question: A car, moving at constant speed of 50 m/s, decelerates uniformly before it stops. The time taken to stop is 2.5 seconds. What is the distance travelled by car when stopping?
Neatly done.
Now, let's enter these information into the program as follow.
Answer:
From the question, we know that
- Initial velocity = 100 ms^-1. (Given)
- Final velocity = 0 ms^-1. (Inferred. "It stops.")
- Time = 2.5 s. (Given)
- Displacement = ?
Neatly done.
Now, let's enter these information into the program as follow.
Great.
The program solved for you. The answer is 62.5m.
Extra: The program even solved for other information(like acceleration and average velocity) using the given points.
