The table is:
t(s) vx(m/s)
0 0
10 23
20 46
30 69
a) from the data in the table, we observe that the acceleration is constant (because the rate of change in velocity is the same for each time interval of 10 seconds), so we can choose just one interval and calculate the acceleration as the ratio between the change in velocity and the change in time. Taking the first interval, we find
b) To find the jet's acceleration in g's, we just need to divide the acceleration in m/s^2 by the value of g, the acceleration of gravity (9.81 m/s^2), so we find
c) the wheels leave the ground when the jet reaches its take-off velocity, which is 82 m/s.
At t=0s, the velocity of the jet is 0. We know that the acceleration is constant (a=2.3 m/s^2), so we can find the time t at which the jet reaches a velocity vf=82 m/s by using the equation
Re-arranging and substituting numbers, we find
Electrostatic force changes like the inverse square of the distance (just like gravity).
If you double the distance, you change the force to 1/4 of what it used to be.
After the move, Objects 1 and 2 attract each other with a force of (18/16) = 1.125 units .

Producido a partir de un experimento de laboratorio ido mal, las tortugas adolescentes Leonardo, Michelangelo, Donatello y Raphael viven en las alcantarillas bajo Nueva York. Aunque su sensei roedor, Splinter, aconseja no mostrarse sobre el suelo, los hermanos amantes de la justicia y que comen pizza no pueden permanecer ociosos mientras el malvado Shredder y sus secuaces aterrorizan a la ciudad. Con ayuda de la intrépida reportera April O'Neil (Megan Fox) y su camarógrafo (Will Arnett), las Tortugas salieron a salvar a Nueva York.
