I Suck Balls at Physics...

I got 3 questions due in an Hour... if Anon could help me out I'd be the happiest College Freshman in the world...

1. Michael Jordan fans claim he was able to jump and remain in the air for 2 full seconds from Launch to Landing.  Evaluate this claim by calculating the maximum height that such a jump would attain.  For comparison, Jordan's maximum jump height has been estimated at about one meter.

(I don't even know what this question is asking)

2. A car drives off a 54 m high cliff and lands 130 m away.  How fast was the car going.

3. A skateboarder rolls down a 12 m ramp and is going 7.7 m/s when she reaches the bottom. (a) what is her acceleration, assuming it is constant, (b) If the ramp is inclined 25.0degrees with respect to the ground, what is the component of her acceleration that is parallel to the ground.

...Also none of these factor in wind resistance or any outlying forces...

I know, these are probably really easy, but my teacher is insane and his notes are unreadable.  Also, I've never taken Physics before.

So if you could I'd be forever grateful.

1) It means he spent 1 second reaching the peak, and 1 second crashing down to the ground.  His speed at the peak is obviously 0.  The acceleration is given by default (g).  Thus, given final velocity, acceleration, and time, you want distance.  I'll let you figure out which equation to use.

2) How long does it take the car to fall to the ground?  During this time it moves 130m; that's enough to figure out how fast the car was going.

3) Given initial velocity (0), final velocity, and distance travelled, you want acceleration.  Again there's an obvious equation to use.  Part b is trig.

Physics rarely includes wind resistance of friction.

Come back and post your failing grade. Maybe that'll teach you to find better ways of solving problems than posting on 4chan and following the advice of high school wannabe geniuses.
