Furious 7 - JC Physics Questions

I am going to be honest - I am not a fan of cars and the franchise Fast and Furious. To be even honest, I never wanted to watch this movie because it sounds too tiring to even watch. However, I'm glad I did. Try solving the two physics problems below. If you get the answers correct, you could get your parents to buy you tickets to the movie!  

PHYSIC PROBLEM 1: CAR FLIES OUT FROM SKYSCRAPER

In this scene, Vin Diesel's character, Dominic Toretto threw his Lykan HyperSport car out from the last floor of the Etihad Towers Skyscraper and crashes into an adjacent skyscraper. Would it be possible in real life?

To solve this physics question, we need to know the following:

The Lykan Hypersport is a limited production sports car by W Motors, a Lebanese based company founded in 2012. The car is claimed to have a top speed of 385 km/h.

 

The Etihad Towers Skyscraper has 5 towers, with Tower 2 being the tallest at 277m. The nearest tower is Tower 3. The distance between Tower 2 and Tower 3 is 42.672m.

With this information, let us first consider the downward forces. A plunge from the top storey of Tower 2 of Ethihad Towers Skyscraper would take approximately 7.5148 seconds for the car to reach the ground, assuming the downward acceleration is constant 9.81ms^-2. (t = v-u/a)

Meaning, the car only has approximately 7.5 seconds to reach the adjacent building before it crashes to the ground. Let us consider the horizontal forces. Assuming its final velocity is 0m/s when it reaches the building, the horizontal distance it can travel is 401.83km, way above the horizontal distance of the two buildings. (42.572m)

Hence, this stunt is POSSIBLE in physics. But I'm not suggesting you should try it yourself. 

PHYSICS PROBLEM 2: CAR FREE FALLS FROM PLANE

 

In another reality defying scene, Vin Diesel and his gang dropped their car from an aircraft with the aid of some ultra size parachute. Is this even possible in reality?

To answer this question, we assume the average mass of a car to be 1,500kg and downward acceleration pull from gravity as 9.81ms^-2. We calculated the downward force to be 15499.8N. In order for it to cushion the fall effect, we need a parachute that can exert and upthrust that is equivalent to or bigger than the downward force.

A search online reveals the biggest parachute invented by NASA can take 8897.67N force. Almost half the downward force. Hence, if this happens in reality, chances are the parachute willl fall apart.

Glad I still remember my JC Physics. In case you're bored with the mindless calculations, here's 9 quick reasons why you should watch Fast and Furious 7 - Vengeance Hits Home:

1. Cat Fight Turns Us On - Especially if it's between two hot women

2. Car Models so Exotic You wonder if they're real

3. Filmed Across 3 Different Countries

4. A Buffet of Butts & Boobs

5. Death Defying Stunt

6. The Dual Meaning Ending - The ninjas were chopping onions secretly when Vin Diesel was doing his closing monologue for Paul Walker's character in the show. For those of you who haven't yet watch the movie, I'm not going to spoil it for you by telling you if the character died in the end.
