The projection speed an athlete can generate steadily decreases as the athlete tries to throw with a higher and higher projection angle. However, it is also well known that actual performers in projectile-related sports seldom use an angle of 45�. The only acceleration acting in a projectile motion is the vertical acceleration caused by gravity (g). For example, typical projection angles of world-class shot-putters are around 37°. t = time in seconds. A push-like movement pattern is best in shot put for many reasons, one of significance being that simultaneous motion will result in a more accurate movement due to the body travelling in a straight-line, accuracy is .
Projectile motion is the motion of an object thrown or projected into the air, subject to only the acceleration of gravity. You have perhaps heard that a shotput follows a parabolic trajectory. If we observe the path of the projectile, we find that the projectile moves in a path, which can be considered as a part of parabola. projectiles, such as a shotput. Homework Statement In the shot put, a standard track-and-field event, a 7.30 kg object (the shot) is thrown by releasing it at approximately 40.0 degrees over a straight left leg. .

Example : for the shot put the weight force will be considerably larger ... The total speed v 1 of a projectile at its greatest height is \sqrt {\frac {6} {7}} of its speed v 2 at half its greatest height. Projectile Motion. For example, typical projection angles of world-class shot-putters are around 37°. The path of a projectile is a linear curve round This is due to the fact that the time component in the free fall equation (Ay) is Wit out air resistance, maximum range of a projectile is obtained with an angle of and. simply coasts with the initial horizontal velocity that Randy gave it.

Shot put requires all of the joints in the kinetic chain to move simultaneously in one single movement (Blazevic, 2010). The athlete again follows a uniform circular motion to generate the maximum force on the ball. Proposed Subject usage: Mathematics / Physics (A/AS level), Sports Science (Degree Yr 1/2) Introduction.

A Projectile is any body that has been set on its path by some force and continues in motion by its own inertia. Find the angle of projection.
Wind factors like wind speed and wind direction are also crucial here as they may affect the motion of the projectile. Examples of projectile motion Throwing a ball or anything. The teacher drops a mass and either using ticker-tape timers, or a photogate/motion sensor, provides students with the data to calculate speed . Even so, this produces only a small reduction in the calculated optimum projection angle (to about 42�). u = initial velocity in metres per second. Some researchers have noted that in shot-putting the landing is about 2 m lower than the launch. The combination of constant horizontal velocity and constant downward

Why does a shotput follow a parabolic arc, and not some other curve? However, it is also well known that actual performers in projectile-related sports seldom use an angle of 45°. Experiments have shown that the projection speed an athlete can generate decreases with increasing projection angle, and that this substantially reduces the optimum projection angle. like [s] for seconds and [m] for meters): It takes a little over 1.4 s for the shotput to drop from a height of
