Question

Part C) Using Principles of Physics including work and kinetic energy, explain why athletes always release the javelin some distance behind the line.

Part D) The best athletes manage to throw over 90 meters. Good throwers always throw their javelin so that it flies up some substantial height above the ground. Using Principles of Physics, explain why this benefits the athlete.

Part E) The best javelin throwers are always large people with very strong bodies. Use principles of physics including Work and Kinetic Energy to explain why such people are best at throwing javelins.

Explanation / Answer

since conservation of momentum

while throwing if they are running they are having more moemtun tthat can be transefered which inturn increase its speed of javelin

sinc e to get best maximum range of given velocity we get angel of projection is 45 degrees with horizontal
