A rectangular tank with length 3 m, width 2 m, and height h m is full of a certain synthetic oil whose mass density is 1 3 kg/m3 . If the work required to pump all of the oil to the top and out of the tank is 90 J, how tall is the tank (i. e., what is the value of h)? Use 10 m/s2 for the acceleration due to gravity.

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.
