A toy rocket moving vertically upward passes by a 2.2m -high window whose sill is 7.0m above the ground. The rocket takes 0.17s to travel the 2.2m height of the window
part a) what was the launch speed of the rocker ? assume the propellant is burned very quickly at blastoff
part b) how high will the rocket go ?
