Those who know Physics...
    #4989351 -

I'm trying to figure out this problem, but I can't.

I gotta leave for a test on this stuff in about 25 minutes.

Bill throws a 50.0g ball downward from a height of 2.00m. The ball is traveling at 8.50 m/s just prior to hitting the ground. With what speed did Bill throw the ball?

I can't find an equation that doesn't require both the initial velocity and the time.

Any help would be greatly appreciated.

The equations I have that might be of use would be...

S = .5(Vi + Vf)t
S = Vav t
Vf^2=Vi^2 + 2as
Vf = Vi + at

Wouldn't you use the basic gravitational acceleration equation to figure out how fast it's going when falling from that height, and then just figure out the difference between the answer that yields and the speed given?

He didn't just drop it, he threw it.

Yes but it would accelerate all the same, would it not? Subtract the end result from acceleration from that height out of the given speed upon hitting the ground.

At least, that's what I'd do, and I aced physics in high school.

Well how would you do it? If you could type it out, or at least the start that would be great.

Makes sense to me..... :shrug:

One more.

Megan's mass is 28.0kg. She climbs 4.8m up the ladder of a slide and then slides down, reaching a speed of 3.20m/s at the bottom. Determine the work done on Megan by the force of friction.

Ah yes, of course, potential energy - kinetic energy. Makes sense.

Hehe, I loved physics. It was the easiest class I ever took. The teacher had some issues though, man did you not want to piss that guy off. A gregarious, but tempermental italian white man. I think he might have worked at NASA at some point.

Basically physics is a class where you learn concepts and solve equations that your required algebra classes have drilled the necessary skills for into your head long ago. And to make things even better, I programmed many of the equations into my calculator so I could just input the variables and have it do the work for me. I love being both lazy and smart, they mix together quite well at times.

If you have a Texas Instruments graphing calculator capable of being programmed, I'd recommend you do the same, it's a real timesaver on homework. Assuming you dont need to show excessive amounts of work to get credit.
