Solve the all parts of given problem:
Problem: A home run is hit in such a way that the baseball just clears a wall 14.0 m high, located 118 m from home plate. The ball is hit at an angle of 33.0° to the horizontal, and air resistance is negligible. (Assume that the ball is hit at a height of 1.0 m above the ground.)
Part A: Find the initial speed of the ball.
Part B: Find the time it takes the ball to reach the wall.
Part C: Find the velocity components of the ball when it reaches the wall.
Show how you get the answer, so that I can better understand how to do it.
An isolated conductor of arbitrary shape has a net charge of+7.7 x 10-6 C. Inside the conductor is a cavity within which is a point charge q = +3.9x10-6 C. In Coulombs, what is the charge (a) on the outer surface of the conductor and (b) on the cavit..
