A baseball player standing on the ground throws a ball straight up. The ball leaves the player's hand with a speed of 15.5 m/s and is in the air for 3.30 s before hitting the ground. How high above the ground was the baseball player's hand when he release...

While standing on top of a 323 m tall building, you see Iron Man flying straight down toward the ground at a speed of 35.0 m/s. Just as he passes you, you drop a can of Dr Pepper off the roof. How fast is the can going when it passes Iron Man?

A charge of 16.0 nC is uniformly distributed along a thin, flexible rod of length 31.0 cm. The rod is then bent into a semicircle, evaluate the electric field strength from the centre

Two capacitor plates are equally and oppositely charged. They are separated by 6.30 cm. An electron is released from rest at the surface of the negative plate and, at the same time, a proton is released from rest at the surface of the positive plate. Wher...

There is a thin rod of length L. The top half of the rod has a charge +Q, and the bottom half of the rod has a charge -Q. Evaluate the electric field E at a distance r = 7.40 cm if L = 7.30 cm and Q = 3.50 nC

Three point charges are located away from a dot. charge 1 is 3 cm north of the dot and is 2.1 nC. Charge 2 is 5 cm east of the dot and is -5nC. Charge 3 is -10nC and is located 45 degrees northeast and 5.831 cm away from the dot. What is the net electric...
