Answer:
Suzie is 3 blocks north of where she started
Explanation:
Displacement is the minimum distance between the initial and final point of motion.
Here, Suzie first walks 3 blocks north. From there she walks 4 blocks east. Then 2 blocks to the east then 2 blocks north and then 2 blocks east. She covered 4 blocks east toward west. This is the same distance she covered traveling east. But she is 2 blocks north. From there she traveled a block south to the pizzeria and another block to her friends house. She covered the two block she had traveled north.
Hence, Suzie is 3 blocks north of where she started.
The ball's vertical position in the air at time
is
The ball is at its original height when , which happens at
Meanwhile, the ball's horizontal position at time
is
So when the ball reaches its original height a second time, the ball will have traveled a horizontal distance of
(which you might recognize as the formula for the range of a projectile)
To reach a distance of , the initial speed
would be
