A fireworks shell P fired in a vertical trajectory has a y-acceleration

A fireworks shell P fired in a vertical trajectory has a y-acceleration given by ay = -g -kv2, where the latter term is due to aerodynamic drag. If the speed of the shell is 15.5 m/s at the instant shown, determine the corresponding values of r, r, r, 0, 0, and 0. The drag parameter k has a constant value of 0.009 m Answers: 174 m 111 m r = 206.4 m j = 8.34 } = i -4.93 0 = i .568 0 = .0633 = i .0261 m/s m/s rad/s 0 rad/s
