object thrown up with initial velocity of 15 m/s and horizontal velocity of 18 m/s, how much time is required to reach the highest point of trajectory? Vox = 18 y = yo + vosint + 1/2gt^2

this is the problem: A projectile is fired with an initial speed u and at an angle of elevation ®. The air resistance is known to be quadratic and the terminal velocity has a magnitude vt. Show that the equations of motion for the projectile can be cast into the form y' = f (t; y); t >=...

Hi, I need to plot as a function of time, the altitude of a capsule bringing astronauts back from space. I have all the values required in order to calultate it but I'm not sure how i plot it as a function of time? Is it simply a differential matter? Your help is much appreciated...

Q.Ted Williams hits a baseball with an initial velocity of 120 miles per hour (176 ft/s) at an angle of q = 35 degrees to the horizontal. The ball is struck 3 feet above home plate. You watch as the ball goes over the outfield wall 420 feet away and lands in the bleachers. After you congratulate...

Hi: I'm to write a program ("game") in which two tanks take shots at each other, with a user who inputs firing angle, gravitational acceleration and the like, I'm sure you've all heard of it. Anyway, I'm having trouble in dealing with air resistance. Without knowing too much on the...

A projectile fired from ground level at 25 m/s hits the ground 31.25 m away. At what angle was it fired? I wrote equations for t for both x and y t = delta x / velocity x t = 2 * viy/a and set them equal to each other to eliminate t and replaced velocityx with cos(theta)*25 and...

I have no idea what formulas I'm supposed to use here, or possibly how to use them... any help would be great... Protons are projected with an initial speed vi = 9.73 103 m/s into a region where a uniform electric field E = (-720 j) N/C is present, as shown in Figure P23.49. The protons are...

A car in a roller coaster moves along a track that consists of a sequence of ups and downs. Let the x-axis be parallel to the ground and the positive y-axis point upward. In the time interval from t=0 to t=4 s, the trajectory of the car along a certain section of the track is given by (look...

I need Help! I've got this question which I can't Answer : If the mass of the Sun is reduced by 1% and the Earth's velocity is also reduced by 1%, what will be the trajectory of the Earth?

My question reads as such: So far, I've managed to resolve the two equations of motion, for the X and Y directions, and t final. They are as such: x(t)=v0*t y(t)=(1/2)*(q*E/m)*t^2 tfinal= L/v0 My problem is synthesizing these into one equation that solves for E. Any help would be...

A tennis player standing 12.6 m from the net hits the ball at 3 degrees above the hoizontal. To clear the net, the ball must rise at lease 0.33m. If the ball just clears the net at the apex of its trajectory, how fast was the ball moving when it left the racket? would it just be...

I need some help with the problem. A shell is shot with an initial velocity v0 of 20 m/s, at an angle of 60 degrees with the horizontal. At the top of the trajectory, the shell explodeds into two fragments of equal mass. One fragment, whose speed immediately after the explosion is zero...

Please help me with this problem! :confused: I can't seem to get it set up quite right. A high diver leaves the end of a 5 m high diving board and strikes the water 1.3s later 3 m beyond the end of the board. Considering the diver as a particle,d etermine a) her initial velocity, B. the...

I am writing a graphics program to model projectile motion of a ball being thrown. What I am looking for is an equation that will give a specific X and Y coordinate, in the parabolic path, for any specific time it is given, and a arbitratry velocity and angle. For example, if I give it...

I have always thought that a meteor enters the Earth's atmosphere and impacts the ground (if it doesn't disintegrate first) at an angle. I saw something a few months ago which has bothered me ever since. I live in an area of farms, cow pastures and wilderness preserves. I was driving one...

What makes a trajectory (orbit) bound?

im reading about the subject Trajectory Triangulation from here: http://www.faculty.idc.ac.il/avidan/Traj-Trian-Pami.pdf i haven't finished reading (so perhaps it explained in further pages) and i encoutered to words 3D line. now i presume D represents dimension so the next question is how...
