1) 45° is the ideal launch angle for projectile motion that gives the greatest horizontal range. Complementary angles will give the same range but will be less than the range for 45° Pick two complementary angles such that the sum of the angles is equal to 90°. Prove numerically the range is identical for both cases. Will the time aloft be the same for both angles? 2.) For the same two complementary angles assume the projectiles leave from a cliff and land 10.0m below the starting point. Prove the ranges in this case are not identical.

Let's say the launch speed is constant, but you can adjust the launch angle, and again we will deal with the special case where the landing point is at the same vertical level as the launch point. In this case, which launch angle will produce the maximum range? 45 degrees, angle less than 45 degrees, angle greater than 45 degrees, or does it depend?
Problem 1: A cannon ball has been shot from a 10 height with an initial velocity of 15m/s, what is the horizontal distance from which it land? What is its time of flight?Problem 2: A man has been use to fire a cannon with an initial speed of 15 m/s at anangle of 42 degrees from the horizontal surface. What is the maximum heigh the manwas able to reach? What is the range of the man where the canon was shot? What isthe total flight of the man?What is the conclusion?
In 2007, Michael Carter (U.S.) set a world record in theshot put with a throw of 24.77 m. What was the initial speedof the shot if he released it at a height of 2.10 m and threw itat an angle of 38.0º above the horizontal? (Although themaximum distance for a projectile on level ground is achievedat 45º when air resistance is neglected, the actual angle toachieve maximum range is smaller; thus, 38º will give alonger range than 45º in the shot put.)
the leprechaun in the shamrock patch was named O'Malley and since he was disrupted from sitting in his patch he decided to go off and play a round of his favorite sport in where leprechaun kick a gold coin from a tee into a post 317m away. if he kicked the coin at an angleof 60 degree at a velocity of 60 m/s how high was the arch of the rainbow created by the trajectory? how long did it take to get to the pot?
A helicopter flying horizontally at an altitude of 3 km is on course to pass directly over a cell tower.At the instant when the helicopter is 5 km from the tower, the distance between them is decreasingat the rate of 160 km/h. What is the helicopter’s speed at that time?
Construct motion diagrams showing the velocity and accelerationof a projectile at several points along its path, assuming(a) the projectile is launched horizontally and (b) the projectileis launched at an angle u with the horizontal.
In a projectile motion, the horizontal range and the maximum height by the projectile are equal. 1) what is the launch angle? 2) if everything else stays the same, how should the launch angle, θ0 , of the projectile be changed for the range to be halved?
A projectile is fired at an angle of 34.5 degrees with an initial velocity of 62.5 m/s. What is it's initial vertical and horizontal velocity? What is it's maximum height? What is the total time? What is its horizontal range?
A man starts walking north at 4f t/s from a point P. Five minutes later a woman starts walking southat 5f t/s from a point 500f t due east of P. At what rate are the people moving apart 15m after the womanstarts walking.
An object is projected straight upwards with an initial velocity U. If T is the time taken to return to the point of projection, H is the maximum height and g is the acceleration due to gravity, derive how to solve for: (a.) time of flight, T, and (b.) the maximum height, H, that the projectile can achieve.
A projectile is fired in such a way that its horizontal range is equal to 3.5 times its maximum height. What is the angle of projection?
In a game war, one team sets base on a cliff 15m high and 60m away from the oppenents base. At what velocity must the attack be launched so that the lower base will be hit? The initial launch is at 20 degrees below the horizontal. If the attcking team launches their attack with velocity of 10 m/s, at what angle and manner should the attack be done?
