Question

2. A can of RC cola has an unknown internal pressure. The can is 12.3 cm tall and sits on a table edge 1.10 m off the ground. A small hole at the bottom of the in the can causes a jet of cola to shoot out with the initial spray landing 8.29m from the can. kg Assume the density of cola is 1045 m3 a. Solve for the initial velocity of the cola stream leaving the can. (17.5 m/s) b. Solve for the pressure inside the can. (2.5 atm)
