MNTC 313 – Assignment 3

1 of 2

A common situation dealt With in engineering and physics is that of projectile motion. The

equation for the height of a projectile, 𝑦 [m], is:

𝑔 = Acceleration due to gravity: 9.81 m/s2

𝑡 = Time (seconds)

𝑉0 = Initial Velocity of Projectile (m/s)

Ѳ0 = Launch Angle (degrees)

𝑦0= Initial height of the projectile (m)

The equation for the vertical velocity of the projectile, 𝑥 [m], is:

𝑉𝑦 = −𝑔𝑡 + 𝑉0 sin(Ѳ0

).

Write a program using C/C++ to determine the projectile motion (height, vertical velocity) at a

certain time.

Your code should then employ the following logical conditions:

• If time is greater or equal than zero, first print “Projectile released”

o Print the position and velocity value with the following format:

“Position: xx.xx meters”

“Velocity value: xx.xx meters/second”

o If the projectile has a Vertical velocity greater or equal than zero, print “Projectile

ascending”

▪ If the vertical position of the Projectile is greater or equal than the initial

vertical position, print “Projectile above initial position”

o Or, if the projectile has a negative vertical velocity, print “Projectile descending”

▪ If the vertical position of the projectile is greater or equal than the initial

vertical position, print “Projectile above initial position”

▪ Otherwise, print “Projectile below initial position”

• Or, if time is lower than zero, print “Projectile not released”

Your output must look like:

10,10,45,10

Projectile released

Position: -409.82 meters

Velocity value: -91.03 meters/second

Projectile descending

Projectile below initial position

And for negative time must look like:

-10,10,45,10

Projectile not released

Note: The first line in each example above contains sample inputs passed via the scanf()

statement. Your program should Function properly for any inputs. A starter code file has been

provided on OnQ. Download the file, and copy and paste its contents into a new .c/.cpp file in

your IDE. Use pi = 3.14.
