Mark off and measure the distance of the throw. Time the throw with the stopwatch. This will give you the feet per second. If you want miles per hour take that and multiply by 0.68
The answer is 45 degrees. If given the same velocity, and thrown at say...10 degrees, to the ground, then the distance it would travel is the same as the distance it would travel if it were thrown 80 degrees. Complementary angles end up at the same distance horizontally.
Because distance can be measured in any direction. For example, if I throw a ball -- it could travel a distance of 16 feet (5 metres). The direction I throw it depends which way I'm facing !
To put it shortly... yes.
Yes, throwing the ball requires a force, and work is done when a force moves a mass over a distance.

some typical experiments would be anything to do with an object moving in a particular direction at a set distance. So for example you could throw a tennis ball and time it from the second it was released from your hand to the second it stopped and measure the distance from where you threw the ball to where it stopped, then divide that distance by the time is took to stop there. Simply change the object moving for other experiments.
When a ball is dropped, it no longer has potential energy. Before it drops, you can calculate the potential energy (= mgh); to actually measure this, you would have to measure the force, and multiply that by the distance.
Yes, because if it is a small ball then you can grip it better therefore allowing you to throw it farther. If it is a college or high school ball you must have big hands to throw it a decent distance.
When you throw the tennis ball, it flies for a distance before dropping down because when you throw the tennis ball, you use force, which is transferred to the tennis ball, which then converts to kinetic energy (movement energy), to allow the tennis ball to go far.
I guess use a high speed camera Time it and measure the distance travelled.
