•CONCLUSIONS:
•Horizontal range is greatest for the throw angle of 450
• Horizontal ranges are the same for angles θ and (900 – θ)
4.83 /70 20 respectively. How do you get them to land on the same position at the same time?
Given:
Red bird Yellow bird
Initialvelocities
Shootingangles
Ranges
Times
The yellow bird will be fired after the red bird 0.60 seconds, then they will
land on the same position at the same time
0.60 sec
Yeah!!
Thank you for watching
Any question?
