From a balcony of a building located at the dead-end of a street, John is planning to hit people coming toward his building with flowers. For this, John makes a red-colored mark on the road so that the moment he sees a person at that mark he throws a flower at a speed of 5ms−1 at an angle of 60o with vertical. Assuming that people approach the building at 3ms−1 and if the distance of the point where flower hits a person from the red-colored mark is 10m: (a) find the distance of red-colored mark from the base of the building,
(b) find the height of balcony from the ground, and
(c) just before the flower hits a person, find the horizontal and vertical components of its velocity.

Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. in essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. suppose a current of 480.ma is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for 46.0 seconds. calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. round your answer to 3 significant digits. also, be sure your answer contains a unit symbol. ×10μ
