You are assigned the design of a cylindrical, pressurized water tank for a future colony on Mars, where the acceleration due to gravity is 3.71 meters per second per second. The pressure at the surface of the water will be 125kPa , and the depth of the water will be 14.1m . The pressure of the air in the building outside the tank will be 86.0kPa .
Find the net downward force on the tank's flat bottom, of area 2.50m^2 , exerted by the water and air inside the tank and the air outside the tank.
a projectile is fired with an initial velocity of 15 m/s at an angle of 37 degrees. At t=2 s, find the vertical and horizontal positions of the projectile
A potter's wheel is rotating at 3.2 rad/s in a counterclockwise direction when the potter turns it off and lets it slow to a stop. This takes 26 seconds. What is the average angular acceleration of the wheel during this time?

A person with mass m1 = 60 kg stands at the left end of a uniform beam with mass m2 = 107 kg and a length L = 3.5 m. What is the location of the center of mass of the system
A particle with a charge of q = -5.10 nC is moving in a uniform magnetic field of vec{B}=( -1.24 T ) hat{z}. The magnetic force on particle is measured to be vec{F}= ( -7.60×10-7 N )hat{y}.
Charge of -3.30 nC and a charge of -6.25 nC are separated by a distance of 40.0 cm. Find out the position at which a third charge of +7.60 nC can be placed so that the net electrostatic force on it is zero.
