To actually lift off the ground, a plane must accelerate uniformly from rest to +21.0 m/s for 30 s. If the plane is taking off on a
runway 5.00 km long, which of the following statements is true?
The plane will take off safely because there is just the right amount of runway distance.
The plane does not have enough distance to take off.
You cannot tell from the information provided.
The plane has more than enough distance to take off.

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
