Two balls are thrown from a height of 10 m. The blue ball is thrown at a horizontal speed of 10 m/s while the red ball is thrown at a horizontal speed of 20 m/s. If both balls are thrown at the same time, which reaches the ground first?
The hit at the same time!
Definition of acceleration
What is change in velocity over time

viy = 0 m/s
vix = 8 m/s
Name three vectors
What is displacement, velocity, acceleration, force, momentum, etc
