Lets analyze the wording of the problem:

- A coin will be thrown into the air to fall into a dish “…you toss a quarter into a dish…”.. then it is a projectile problem.
- The coin should land into a dish that is in a higher height than were the coin tossed is. We can take the height of the tossed coin as y1=0 m (because the height of dish needed is from where the coin left the hand) and the height of the dish as y2=h.

What are the given information:

- initial velocity (Vo) = 6.4 m/s.
- Angle of projected coin = 60°
- Δx=2.1 m
- The height where the coin (y1) assumed to be 0 m

What the problem need:

- The height where the dish is (y2=h).
- The vertical component of the final velocity.

SOLUTION:

- The projected coin path could be seen in the below diagram:
