Roger sees water balloons fall past his window. He notices that each balloon strikes the sidewalk 0.59 s after passing his window. Roger's room is on the second floor, 10 m above the sidewalk.
How fast are the balloons traveling when they pass Roger's window?
Assuming the balloons are being released from rest, from what floor are they being released? Each floor of the dorm is 5.0 m high.
The position of a stone dropped from a cliff is described approximately by x = 5t^2 , where x is in meters and t is in seconds. The +x direction is downwards and the origin is at the top of the cliff. Find the velocity of the stone during its fall as a function of time t.
Calculate the magnitude and direction of the electric field 0.45 m from a +7.85 x 10–9 C point charge.

Suppose you adjust your garden hose nozzle for a fast stream of water. You point the nozzle vertically upward at a height of 1.8 m above the ground (. When you quickly turn off the nozzle, you hear the water striking the ground next to you for another 2.6 s .
What is the water speed as it leaves the nozzle?
What is the change in potential energy when a +3.5 C point charge was moved from a negative plate to a positive plate with a potential difference of 8V?
What is the magnitude of the electric field between parallel plates with 25 V of potential difference and placed 25 cm apart?
A point charge q1 = +2.80 µC is at origin. How far should the second point charge of +5.20 µC be placed to have electric potential energy of 0.600 J?
A point charge has a charge of 8.00 x 10-11 C. At what distance from the point charge is the electrical potential (a) 12.0 V? (b) 24.0 V?
1. Two charges Q1=-5 NC and Q2=-7 nc are separated by 8 cm. Calculate tHe electric potential at point.
2. A research van de Graaf generator has a 2.50 mm diameter sphere with a charge of 6.00 UC on it.
