Q I have a nine inch wheel rotating between 300 and 1200 rpm. The wheel
is approximately 2.25 inches wide. I want to place (pinch against the
wheel) a 145 gram projectile (baseball) on the wheel and calculate the
mph it will be traveling at 55 feet from the wheel. Please show all the
e 145 grams
These solutions may offer step-by-step problem-solving explanations or good writing examples that include modern styles of formatting and construction
of bibliographies out of text citations and references. Students may use these solutions for personal skill-building and practice.
Unethical use is strictly forbidden.
1. The angular speed of the wheel is not known. We are just give a range. Thus, the solution is given using this range of initial velocities.
2. The balls comes off horizontally and is subjetc to gravity
3. The details of the interaction between the wheel and the projectile (ball) are not given. I assume that the balls comes off at the tangential velocity of the wheel
4. Details of the size of the projectile are not given. Thus rotaional kinetic energy of of the ball...
