Angular Projectile Motion
How about video?
Velocity and Acceleration of the Car
Example:
Part A
If a car is accelerating at 2.6822m/s^2 [E] for 8.80s with an initial velocity of 37.9984m/s [E] and is projected from a ramp at an angle of 35 degrees to the horizontal. How far will it travel?

Part B
Will the car land on a yacht that is moving at speed of 35.7632 m/s [E] and is already 33.3m away from the car just as it leaves the ramp?

1. Operating loan < 50% value of unsold inventory

2. Expenses (not including P+I payments) < 65% gross revenue (averaged over past four years)

3. Machinery investment < 1.5x gross revenue per acre, with maximum 40% debt to book value, or leases < 10% of gross revenue

4. Equipment debt paid < 5 years if all net farm income directed towards payments

-Since there is no force affecting the car in the horizontal direction, its' horizontal velocity is maintained after leaving the inclined plane.

Angular Projectile Motion
-How to calculate the horizontal distance of an object with an initial horizontal velocity at an angle to the horizontal
Learning Goal

When solving angular projectile motion problems, consider the following steps:
Horizontally:
1. Calculate the acceleration of the object horizontally.
2. Calculate the angle of the ramp to the horizontal.
3. Find the time between the moment you calculated
the acceleration and the instant before the object leaves the ramp.
4. Use the calculated acceleration and multiply it by the time found earlier to find the initial velocity.
5. Calculate the horizontal distance the object will travel.

t= 8.80s the time the car accelerated for before leaving the ramp
a x t =velocity the instant the car leaves the ramp
2.6822 m/s^2 x 8.80s = 23.6034m/s
*8.80s was measured from the time when the car was moving at 37.9m/s to when the car left the ramp
23.6034 +37.9984 =

Since we can't have 2 unknowns, we'll find a time where we know V which is half way; V = 0m/s. Since this way we'll only calculate the time for half the journey, we'll multiply the answer by 2 giving us the full duration.

Career: Visual Effects Artist
The Nature of Work:
Visual-effects artists create special effects, animation and do visual clean-up for upcoming films and commercials
Visual-effects artists must ensure that visual effects are added carefully so the viewers don't know this was done
Most visual-effects artists work 10 hours long to meet deadlines

Salary
-According to Service Canada, Canadian workers in the Geographic Designers and illustrators group earn $35, 000 annually

-In the United States, visual effects artist can earn, on average $60, 000.
The Goal
-The goal of all visual effects artist is to keep the audience focused on the story and the characters
-Good visual effects artists are judged by their ability to make the impossible seem absolutely real

Good or Bad Physics?
Terrible Physics:
In the movie the car had travelled 33.3 m, but through our calculations we came to a conclusion that the car should have travelled 363m. This is more than 10 times the distance the car travelled in the movie.
IT WILL LAND,
But in the water
Therefore the car will travel 363.8252 m
