Physics – Projectiles Motion at an Angle
Formulas:
1) d = (1/2) (vf + vi)t
2) d = vit + (1/2)at2
3) d = vft – (1/2)at2
Date: _______________________
4) vf2 = vi2 + 2ad
5) a = (vf – vi)/t
You kick a soccer ball at an angle of 40° above the ground with a velocity of 20m/s.
1. Calculate the individual vertical & horizontal components of the initial velocity.
a) How high will it go?
Are we thinking vertical or horizontal?
The velocity at the maximum height is ___________________
b) How much time does it spend in the air?
Are we thinking vertical or horizontal?
How much time will have gone by at the maximum height? ________________
c) How far away from you will it hit the ground?
Are we thinking vertical or horizontal?
Which quantity stays the same regardless of if we calculate something vertical or horizontal?
____________
d) What is the ball’s velocity when it hits the ground?
Are we thinking vertical or horizontal?
