did you read the whole problem? i think it is a little more than complicated than you make it sound.

Homework Statement A storage reservoir is continuously filled through a pipe delivering 2.2cfs. The reservoir is circular in shape with a diameter of 20 ft. The height of the tank is 12ft. A pump operates for the last 5 minutes of successive 20 minute intervals, draining out 350 cubic feet of...

Homework Statement Two identical point charges (Q=3uC) are situated 60cm apart on the y-axis equidistant from the origin. A 2uC point charge lies at 40cm on the + x-axis. What is the magnitude and direction of the net force on the 2uC charge. Homework Equations F= kq(1)q(2)/r^2...

Homework Statement a ball is thrown horizontally with a speed of 15m/s at a point 2.0m above the level ground. how far will it go before it hits the ground Homework Equations Dt = (Vi)(t) + (1/2)(a)(t^2) The Attempt at a Solution i think this is the formula to use, however, i...

what about average acceleration? is that distance/time?

Homework Statement car moving 12.0m/sec eastward on straight road. inside car, bug is flying eastward at 2.0m/s relative to the car. how fast is the bug moving relative to the road? repeat for the bug moving westward. Homework Equations The Attempt at a Solution i assume the...

i got it. i goofed when i tried being slick and figured 3600s^2 = 60^2/hr^2

how to do the seconds can i do (385.8267717in/s^2) X (60s^2/1hr^2) = 1388976.378in/hr^2. this answer is not correct

Homework Statement 9.8m/s^2= ? in/hr^2 Homework Equations The Attempt at a Solution (9.8m/s^2)X(1ft/.3048m)=(9.8ft/.3048s^2)=(32.15223097ft/s^2)X(12in/1ft)=(385.8267717in/s^2)

and that number divided by 3600sec/hr = 36.45377----ft/sec.

so 24.85484769 X 5280 = 131,233.59580ft/hr. ?

aw that's cool. atleast i have an answer to check my work by thanx!

(40km/1h)x(1mile/1.609344km)=24.85484769m/h ??

cant get around this problem: convert 40km/h to ft/sec.
