Question

Figure 1: Diagram without and with gravity The models without and with gravity are illustrated in the figures above for, and they can be described using the differential equations: mv + um' = 0 and mv' +mg+um² = 0. Solve both differential equations with respect to the speed v(t). a) Without gravity. Solve the differential equation with respect to p'a the speed as a function of the mass. b) With gravity. Solve the differential the speed as a function of time. equation with respect to p'a
