"In a chase scene, a movie stuntman is supposed to run right off the flat roof of one city building and land on another roof 1.6 m lower."
"If the gap between the buildings is 4.5 m wide, how fast must he run? "
Homework Equations
Vf^2 = V0^2 + 2a (Xf-X0)
This might not be the right equation, but it's the one I've been trying to use
The Attempt at a Solution
Vf^2 = 2(9.8)(4.776)
4.776 is the hypotenuse of the 1.6m and 4.5m distances
bmarvs04 said:Ok thanks,
So in order to solve for the vertical velocity, I used the equation Vf^2 = 2(9.8)(1.6) = 5.6m
Then do I use trig to solve for horizontal velocity? In other words, Horizontal Velocity = cos(70.4268)*5.6 where 70.4268 is the downward angle of the triangle formed by 1.6m and 4.5m.
I got 1.876 m/s as my answer, does this sound right?
Thanks
The average velocity required to successfully jump from one building to another will vary depending on the distance between the buildings and the height of the buildings. However, it is estimated that a velocity of at least 20 miles per hour is needed to clear a gap of 20 feet between buildings.
Air resistance, also known as drag, can significantly impact the velocity needed for a building-to-building jump. As the velocity increases, so does the amount of air resistance. This means that a higher velocity is required to overcome the drag and successfully complete the jump.
Yes, it is possible to calculate the exact velocity needed for a specific building-to-building jump using the principles of physics. Factors such as the distance between buildings, height of the buildings, and air resistance can be taken into account to determine the precise velocity needed for a successful jump.
Yes, a person can increase their jumping velocity through training. Techniques such as plyometrics, resistance training, and proper form can help improve a person's jumping ability. However, it is important to note that attempting dangerous jumps between buildings is not recommended and can result in serious injury or death.
Yes, there are several safety precautions that should be taken when attempting a building-to-building jump. These include wearing appropriate safety gear, ensuring the jump is legal and authorized, and practicing proper technique. It is also important to have a trained professional present and to never attempt a jump that is beyond one's abilities.
