Anybody good at physics I need help!!!!!!

[Mr.meyhem 10+ year member]

#1.) Object being launched at 20 m/s at an angle of 30*. What will the highest vertical height be?

How far away will it land?

And what is the final velocity (right before hitting the ground)?

#2.) same questions as #1. but its 3 m/s the vertical height is .2m and the total distance is 1.5m

#3.) A tennis ball is hit from .5m above ground at 20m/s at an angle of 15*

there is a wall 6m away.

how high off the ground will the ball hit?

#4.) if a skier is jumping of a ramp that is 51m away from the next ramp and the skier lands at an angle downward of 43* at 23 m/s what was the initial velocity of the skier? (other than 0)

Thank you for any help!!!!!!!!!!!!!!!!!!

let me find my formula sheets im lazy to work out from scratch

 

[Mr.meyhem 10+ year member]

OMG thanks man!!! if u do good ill send ya 5 bucks paypal lol.

Assuming no wind resistance and 9.81m/s accel. due to gravity right?

 

[Mr.meyhem 10+ year member]

yeah lol. and I'm suppose to use 9.8 m/s gravity.

Lol cheating on your homework?

 

[Mr.meyhem 10+ year member]

no its on a test i need to finish!!! //content.invisioncic.com/y282845/emoticons/up2something.gif.dd110ecf3ae4b76050d87598f2f8de7c.gif lol

for 1) total height is 5.0968m, total distance is 35.3119, and the velocity will be 20m/s unless you only want the x or y component.

k thanks man

use 5.102 for distance (recalculated with 9.8 instead of 9.81) and 35.33 for distance. Texting you now.
