U of O Physics Problems
Two cannons, one aimed
(left) from horizontal, the other aimed
(right) from horizontal, are simultaneously fired toward each other .
- a.
- In order for the two projectiles to collide, at some point in time the
y components of position must be the same. Since the cannons were fired
simultaneously, show that this means the y components of their initial velocities
must also be equal.
- b.
- Given what you showed in part a, and that projectiles are fired from the left cannon at 100 m/s, determine the required initial velocity of projectiles fired out of the right cannon for an impact to occur.
- c.
- If the cannons are 1.3 km apart, when does this impact take
place?
- d.
- Where does it take place? (Give x,y coordinates relative to the
left-hand cannon)
