1
Q
What is Uy (vertical component, starting velocity) equal to?
A
u sin (theta)
2
Q
What is Ux (horizontal component, starting velocity) equal to?
A
u cos (theta)
3
Q
What is Vy?
A
Final velocity in the vertical
4
Q
What is Vx?
A
Final velocity in the horizontal
5
Q
What is Sx?
A
The displacement in the horizontal direction
6
Q
What is Sy?
A
The displacement in the vertical direction
7
Q
What are the rules for landing at the same height?
A
Impact speed = launch speed
Impact velocity with have same angle and magnitude as launch
Vy = -Uy
8
Q
Landing at lower and higher heights
A
See pg 53 and 54
9
Q
What do complementary angles mean for displacement?
A
They will both be the same displacement as they add to 90˚
