A filter filled with liquid is in the shape of a vertex-down cone with a height of 66 inches and a diameter of 44 inches at its open (upper) end. If the liquid drips out the bottom of the filter at the constant rate of 11 cubic inches per second, how fast is the level of the liquid dropping when the liquid is 33 inches deep

Can someone explain to me how to do this problem ?

Aforce of 240.0 n causes an object to accelerate at 3.2 m/s2. what is the mass of the object?

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
