To solve for the initial velocities in the X and Y direction, what must you use?
SOH-CAH-TOA
A toy truck gets kicked at a rate of 20.13 s at 37°. What are the initial velocities in the X and Y?
X=16.10 m/s
Y=12.10 m/s
A show horse jumps at 7.07m/s at 47°. What are the initial velocities in both directions?
X=4.81m/s
Y=5.16m/s
A Rocket was launched at a rate of 35.77m/s at a 45°. What are the initial velocities of x and y?
x=25.40m/s
y=25.40m/s
A soccer player kicks a ball towards the goal at 27m/s and 58°. What are the initial x and y velocities?
x=14.31m/s
y=22.95 m/s
Are Vertical initial velocity x and vertical final velocity x the same value?
Yes they are equal in value
What was the overall airtime of the truck?
Time=2.47s
How long did it take the show horse to reach the peak of his jump?
Time=1.05s
Tup=.53s
What was the overall air time of the rocket? What was the time it took to reach the peak?
t=5.18 s
tup=2.59s
t= 4.68s
tup=2.34 s
Acceleration for X is aways 0 m/s^2
VP for is 0 m/s
Acceleration for Y is always -9.81 m/s^2
How long did it take the truck to reach the peak of the jump?
Tup=1.24s
What was the total distance the rider jumped in a horizontal direction?
D=5.05 m
what was the maximum height of the rocket?
dy=32.87m
If the gollies were 1.77m tall, did the kick go over his head and into the goal, or did it hit the goalie?
dy=26.82m
yes went over his head by 21.05m
What are the steps of solving for full projectiles?
2. Use vertical(y) components to solve for time
3. Divide time by 2 to solve for tup
4. Use both VP and Tup to solve for height
5. Use the overall time to solve for Distance x
What was the maximum height of the truck?
Dy= 7.44 m
What is the hight of the jump in a vertical direction?
D= 1.35m
dx=131.57m
How far did the ball land from the kicker assuming he made it past the goalie?
dx= 66.97m
