Determine the missing X speed.

Determine X and Y speeds.

A football is thrown in the air at 27 m/s 30° from the horizontal. The x and y velocities are 23.4 and 13.5 m/s.

How long was the football in the air?

t = Vf-Vi/a

A kickers starts the football game by kicking the ball 36 m/s 45° from the horizontal. The x and y velocities are both 25.5. The total flight time of the ball is 5.2. How high did the ball go up in the air? (y displacement)

d = Vi(t) + (0.5)(-9.8)(t²)

A javelin thrower releases the javelin at 45 degrees from the horizontal at 31 m/s. Find the velocity in the x and y direction.

A water balloon is launched from a slingshot at an angle of 45 degrees with an initial velocity of 15 m/s. How far is the horizontal displacement of the water balloon?

You first need to find x and y velocities using trig functions then.

Calculate time: t=(vf-vi)/a (using y velocity)

answer will only be half time in the air, so multiply by 2

D = S x T (using x velocity)

A golfer hits a golf ball at an angle of 30 degrees with a velocity of 40 m/s. Determine the horizontal range of the golf ball.

First find x and y velocity of your golf ball using trig functions.

Then find time: t = (Vf-Vi)/a (using y velocity)

This is only half your time, multiply it by 2.

D = S x T (using x velocity)
