Atoy rocket is launched twice into the air from level ground and returns to level ground. the rocket
is first launched with initial speed v at an angle of 45° above the horizontal. it is launched the second
time with the same initial speed, but with the launch angle increased to 60.° above the horizontal.
describe how both the total horizontal distance the rocket travels and the time in the air are affected
by the increase in launch angle. [neglect friction.]
