The x and y coordinates, as a function of time, t, of a projectile (a ball) fired with an initial velocity, v, at an angle of θ with respect to the ground, are given by these formulas:
dx = v. cos(θ).dt
dy =v.sin(θ).dt – (g.dt2)/2 (where gravitational acceleration, g = 9.81 m/sec2)
a. Using these formulas, write a VB/Excel program that displays a table of x and y values for a projectile fired with an initial velocity of 400 m/sec at an angle of 22.8 degrees. (Hint: best to convert to radian measure). As an initial test, the table should contain values corresponding to the time interval 0 to 10 seconds in increments of 0.1 seconds.
b. Modify your program to take user input on elevation, initial velocity and time-step increments.
c. Devise a method to show the time and distance the projectile travelled and lands.
d. Can you determine when the projectile reaches terminal velocity?
this is question that i have to solve but i dont get anything
