Five identical particles of mass m = 0.30 kg are mounted at equal intervals on a thin rod of length l = 1.01 m and mass M = 2.0 kg, with one mass at each end of the rod. If the system is rotated with angular velocity = 60 rev/min about an axis perpendicular to the rod through one of the end...
I have a lab question that I'm confused about:
What can you say about acceleration if the:
a) static coefficient = kinetic coefficient = 0
b) static coefficient = kinetic coefficient does not equal 0
c) static coefficient is greater than kinetic coefficient
A hunter aims directly at a target (on the same level) 120 m away.
(a) If the bullet leaves the gun at a speed of 300 m/s, by how much will it miss the target?
(b) At what angle should the gun be aimed so the target will be hit?
Im havin a little trouble here. I think you are supposed to...
The volume of water would be (43000 people/4)*(1200 L)*(1000 cm^3/L)= 1.29e10 cm^3
Area = (43km^2)(100000 cm/km) = 4300000 cm^2
*btw the final answer must be in cm
h = 1.29e10 cm^3/4300000 cm^2
h = 3000 cm
yea its 26.38888888888 m/s, no it asks for g's in another questions and when I do 7.9/9.8 it says that answer is correct. I wonder if this method is average acceleration or is it instantaneous?
An average family of four uses roughly 1200 liters (about 300 gallons) of water per day. (one liter = 1000 cm3.) How much depth would a lake lose per year if it uniformly covered an area of 43 square kilometers and supplied a local town with a population of 43000 people? Consider only population...
A sports car is advertised to be able to stop in a distance of 44 m from a speed of 95 km/h. What is its [average] acceleration in m/s2? How many g's is this (g = 9.80 m/s2)?
I have 7.9 m/s2, as my answer for average acceleration, but webassign isn't accepting my answer. Can someone help me out?
