(1) Physical and physiological attributes of female team handball players Abstract The main purpose of this article is to review a series of studies (N = 18) on the physical characteristics‚ physiological attributes‚ throwing velocity and accuracy‚ and on-court performances of female team handball players. Studies were selected from a computerized search in electronic databases (Pub Med‚ SPORT Discus) as well as from a manual search. Five main findings emerged from this review: (1) a tall and heavy

or how far she fell. I assumed that she fell about 20 stories‚ or 200 feet (61 meters). If the absence of air resistance is assumed‚ you can find her final velocity using the equation: We know her initial velocity was 0 m/s‚ acceleration due to gravity is 9.8 m/s^2‚ and she fell 61 meters. After plugging in these values‚ the final velocity was determined to be 34.6 m/s. To put this in terms that can be visualized‚ Lois Lane was falling at a speed of about 77mph when superman caught her. I then

Additional Questions 3: Kinematics 1. A balloon is 30.0 m above the ground and is rising vertically with a uniform speed when a coin is dropped from it. If the coin reaches the ground in 4.00 s‚ what is the speed of the balloon? Solution:- Initial velocity of coin = speed of balloon‚ v. by using the equation [Answer: 12.1 ms–1] 2. A car and train moves together along two parallel paths at 25.0 ms–1. The car then undergoes a uniform

Now click and drag the red ball around the screen. Make 3 observations about the blue and green arrows (also called vectors) as you drag the ball around. The vectors appear to have both direct and inverse relationships with each other. When I move the ball one direction‚ both of the vectors move the

State‚ for each of the following physical quantities‚ if it is a scalar or a vector: volume‚ mass‚ speed‚ acceleration‚ density‚ number of moles‚ velocity‚ angular frequency‚ displacement‚ angular velocity. Answer: Scalar: Volume‚ mass‚ speed‚ density‚ number of moles‚ angular frequency Vector: Acceleration‚ velocity‚ displacement‚ angular velocity A scalar quantity is specified by its magnitude only. It does not have any direction associated with it. Volume‚ mass‚ speed‚ density‚ number of

spacing between the Domino’s will provide the fastest velocity for a line of falling Domino’s. II. Background: The Domino C.I.M. lab that we have been assigned brings forth the question of the compression of a line of Domino’s. The question is‚ what set up of Domino’s has the fastest compression time. We intend on testing this by lining up different strings of Domino’s and finding which variable of distance has the greatest compression velocity. This compression of Domino’s shares a very close

HOMEWORK PROBLEMS Chapter-4: MOTION IN TWO DIMENSIONS 1 A particle starts from the origin at t = 0 with a velocity of 6.0[pic] m/s and moves in the xy plane with a constant acceleration of (-2.0[pic] + 4.0[pic]) m/s2. At the instant the particle achieves its maximum positive x coordinate‚ how far is it from the origin? [pic] 2 At t = 0‚ a particle leaves the origin with a velocity of 5.0 m/s in the positive y direction. Its acceleration is given by [pic] = (3.0[pic] - 2.0[pic]) m/s2. At the
