1.
Range of projectile fired with initial angle with horizontal is defined as the horizontal distance travelled by projectile.
Range of projectile is given by
Here, is angle of projection. This relation shows us that range of projectile depends on angle of projectile.
2. R will attain maximum value at the maximum value of .
Maximum value of = 1
i.e,
hence theta = 45 degrees
Hence, Range of projectile is maximum if the projectile is fired at an angle of 45 degrees w.r.t horizontal.

Extra Credit (+3% maximum): The range R of a projectile fired with an initial velocity vo at an angle with the horizontal is given by R = ama where g is the acceleration due to gravity. Find the acute angle such that the range is a maximum.
A projectile P of mass m is fired from a point 0 with initial speed v0 at launch angle φ0 above a horizontal firing range. In addition to gravity, P is subject to the aerodynamic drag force by the surrounding air modeled as a quadratic function of speed where v is the velocity of P and k is a positive pa- rameter. 0 0 We are interested in studying the effect of Faero on various aspects of projectile motion.

Ballistic Pendulum Version Procedure: Fire a practice shot. Locate the landing point on the floor then secure a piece of white paper to the floor (centered about the landing point). Cover the sheet with a piece of carbon paper and tape it down. 1. Shoot the ball at least 5 times. Take care not to disturb the position of the launcher during the shots. 2. Measure the vertical height H of the projectile launcher from the floor. (Use a plumb...

THE EXPERIMENT The speed "." of a ball as it leaves the spring gun will be measured by projecting the ball horizontally (0-0) from a table top at a distance H above the floor. The gun is then elevated at a known angle 8. The position of the target is calculated using the measured value of v. calculated time of flight, and the equations of motion. A successful prediction with the projectile hitting the target means that the following concepts...
help us with the analysis please and also if you could check the calculation if we did it right. thank you so much they are in meters and seconds Analysis 1. For part A (steel projectile), compute the total kinetic energy before and immediately after impact (show your work). Calculate the percent kinetic energy loss by using (KE,-KE)/KE; X 100% 2. In Part D, which launch angle would provide the greatest range? Support with theory. 3. For Part D, calculate...
Please help me correct my MATLAB script code for this problem, thank you!! A projectile PA is launched from point A towards the east with an initial launch velocity voa and an initial lauw angle of 0x. The impact point of the projectile Pa is a point B in a valley with an ordinate, yon, located below the clevation of point A. The launch from point A is instantaneously detected at point B, and a counter projectile P launched simultaneously...
