A child in a tree house is playing with a toy rocket. The tree house is 6.8 meters above level
ground. If she launches the rocket at a velocity of 5.5 m/s at a 60° angle, how far horizontally
from the launch position will the rocket travel before it lands?
A 1.3 m
B. 2.7m
C. 4.8 m
D. 8.4 m

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
