Hey i do not know how to do ANY of these problems i tried using equations and plugged it in and i don't know how to do it please help....(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

1. A golf ball is hit with a velocity of 30 m/s at a 28 Degree angle. what is the max height the ball reaches?

2. A Ball is thrown off a cliff horizontally off a cliff at a velocity of 43 m/s if the ball lands 145m from the base of the cliff how long does it take the ball to reach the ground.

3. A foot ball is projected on a flat surface at a 32 degree angle. If the ball lands 45m from where it started, what is the balls initial velocity

4. A Ball is thrown upward off a cliff at angle of 40degrees horizontally and with a velocity of 35m/s. If it takes 12.5s for the ball to reach the bottom of the cliff, how high is the cliff.

5 A Ball is projected off the top of a 180m high cliff with a velocity of 24 m/s and an angle of 34Degrees. How far from the bottom of the cliff is the ball after 4.2s.

2. Relevant equations

Equations:

Range = Dx = (initial Velocity)^2 (Sin 2 (theta)) / lgl

d = (initial velocity)(t) + 1/2 (g)(t)^2

d= 1/2 (Initial Velocity + Final Velocity)(t)

Final Velocity = Initial Velocity + g(t)

(Final Velocity)^2 = (Initial velocity)^2 + 2(g)(d)

3. The attempt at a solution

I attempted all the problems but got wierd decimal numbers and it didnt LOOK right too much to type for 5 questions... however can someone just tell me which equation to use for each and then if i used it, i will understand if its correct or not... thanks.
