Angle Kinematic
Physics HELP!?
These confuzzle me, help me and can you please post the kinematic formulas too?
1. A soccer player kicks the ball toward a goal that is 27.6 m in front of him. The ball leaves his foot at a speed of 18.5 m/s and an angle of 33.0° above the ground. Find the speed of the ball when the goalie catches it in front of the net. (Note: The answer is not 18.5 m/s.)
2. A diver springs upward from a board that is three meters above the water. At the instant she contacts the water her speed is 9.30 m/s and her body makes an angle of 76.0° with respect to the horizontal surface of the water. Determine her initial velocity, both magnitude and direction
3. A bullet is fired from a rifle that is held 1.2 m above the ground in a horizontal position. The initial speed of the bullet is 1110 m/s. Find
(a) the time it takes for the bullet to strike the ground and
(b) the horizontal distance traveled by the bullet.
Use the equations of motion for projectiles to solve.

Kinematic Tracking of Multiple Targets $114.71 Multiple targets tracking is one of the challenging applications in a wireless sensor network due to targets movement in different directions, targets speed variations and frequent connectivity failures of low powered sensor nodes. If all the lowpowered sensor nodes are kept active in tracking multiple targets coming from different directions of the network, there is high probability of network failure due to the wastage of power. It would be more realistic, if, according to the priority of service, sensor nodes are classified and are kept active. Then, it is possible to reduce energy consumption. In our paper, we propose a distributed tracking framework incorporating sensor network properties which results into a novel service priority based dynamic tracking framework. We simulate our method by a sensor network simulator OMNeT++. We find that our architecture saves energy significantly.

Kinematic Analysis of Robot Manipulators $251.71 A robot manipulator is a movable chain of links interconnected by joints. One end is fixed to the ground, and a hand or end effector that can move freely in space is attached at the other end. This book begins with an introduction to the subject of robot manipulators. Next, it describes in detail a forward and reverse analysis for serial robot arms. Most of the text focuses on closed form solution techniques applied to a broad range of manipulator geometries, from typical industrial robot designs (relatively simple geometries) to the most complicated case of seven general links serially connected by six revolute joints. A unique feature is its detailed analysis of 6RP and 7R mechanisms. Case studies show how the techniques described in the book are used in real engineering applications. The book will be useful to both graduate students and engineers working in the field of robotics. Author: Crane, Carl D., III/ Duffy, Joseph/ Crane, III Carl D.

Kinematics with MicroStation - Ch01D2 Transmission Angle.avi
What are the characteristics of a 2D projectile launched at a 30 degree angle?
A projectile fired at a 30 degree angle has an initial horizontal velocity of 940 m/s and an initial vertical velocity of 96 m/s. It is fired from 20 m above the ground (y=20 m) and lands on the ground, at y=0 m.
If possible, can you show using kinematic equations?
What is the projectile's:
- velocity at its apogee
- total horizontal displacement (x-x0)
- horizontal displacement when it is at its apogee
- height (vertical displacement) at its apogee
I know the velocity is zero at its apogee, but I have no idea how to solve the rest of them. If you could show me how to do the problem I would really appreciate it!
Actually the VERTICAL component of velocity is zero at the apogee. The horizontal component does not change so v = vx0 = 940m/s
To find the horizontal range you need the time of flight. This can be determined from the vertical component. where y = y0 + vy0*t -1/2*g*t^2 Rearranging
1/2*g*t^2 - vy0*t +(y-y0) = 0 So 4.9*t^2 - 96*t + (0 - 20) = 0
Solving we get t = 96 +- sqrt(96^2 -4*4.9*(-20))/(2*4.9) = 19.8s
Therefore x = vx0*t = 940m/s*19.8s = 1.86x10^4m
Now for x when y is ymax
You need the time to ymax Use vy = 0 = vy0 -g*t You get t = vy0/g = 96m/s/9.8m/s^2 = 9.80s
Therefore x = vx0*t = 940m/s*9.80s = 9208m
ymax (above the ground level) can be determined using vy^2 = vy0^2 -2*g*(ymax-y0)
Here vy = 0 so ymax = vy0^2/(2*g) + y0 = 96^2/(2*9.8) + 20 = 490m. (Now the displacement above the release point is 490 - 20 = 470m)
