Chip+The+Flying+Squirrel

Names: Sylvz and Mosez =Chip The XTREME Flying Squirrel! =

**This is Chip. He's an insane in the membrane extreme dare-devil flying squirrel.He's going to be going full speed in his new car without a seatbelt...KIDS DO NOT ATTEMPT THIS AT HOME. In order to keep Chip alive, __you will have to figure out where to place the giant cushion at the bottom of the cliff__. Insane velocity is involved, the radical force of frction, mind-blowing projectiles and of course...awesome collisions. It's time to rock. ** Plastic or Wooden Car (well constructed especially for Chip) Little Stuffed Animal Brick Video Camera + LoggerPro (for accurate velocity calculation) Ruler Cushion
 * Materials Needed: **

Data/calculations: The mass of the car is 1939 grams. The mass of Chip is 70 grams. Distance of cliff is 40.5 inches.

D= 1.028 m Acceleration of fall = -9.8 Vf = 0 Initial velocity.... 0 = vi^2 + 2(-9.8)(1.028) vi = 4.489 m/s

TIME: v^2(1.028)\-9.8 time = 0.46 !

This is the calculation of the drop from the height of the cliff. But since Chip was driving the car, there was an initial velocity of 1.84 right before he fell off. This causes us to split the situation into both VERTICAL and HORIZONTAL calculations.


 * VERTICAL:**
 * D = 1.028 m**
 * a = -9.8 m/s/s**
 * Vi(y)= 0 m/s**
 * Vf(y)= ? m/s**
 * t= 0.46 s**


 * HORIZONTAL:**


 * D= ???**
 * a= 0 m/s**
 * Vi/Vf(x) = 1.84 m/s**
 * t = 0.46 s**

horizontal distance of where it would land =

x = 1.84 * 0.46 + .5 (0) * 0.46^2

Where to place cushion = 0.8464 meters

Reflection/conclusion:

In order to figure out where to place the cushion, the motion of Chip had to be split into two different parts. The horizontal and the vertical motions. By using the LoggerPro application, we concluded that the velocity in which Chip was traveling at was 1.84 m/s. After calculating the time based on the height of the cliff, we used the kinematics equation x = vix*t + 1/2*a*t^2 to solve for the spot where to place the safety cushion. As Chip fell, he went at a downward acceleration of -9.8 due to the force of gravity acting upon him. The horizontal acceleration was essentially 0 because Chip was falling at a constant intial velocity of 1.84 m/s. The collision of the car and the brick caused Chip to continue his horizontal constant velocity because he had no seatbelt. Gravity pushed him downward at -9.8 and he reached the floor at 0.8464 meters, safely and sound! Of course, the force of friction played a role and may have tainted Chip's velocity as seen in the Loggerpro X velocity. Overall though, while Chip was in the air....the force of gravity was the ONLY force acting upon him.
