Derive a function that gives the final speed of the cart as a function of the masses, ramp angle and distance up the ramp that the cart moves. Use conservation of energy to do this-no kinematics or Newton's Laws. I have 3 trials ,, 3 angles and 3 masses (...

Babe Ruth steps to the plate and casually points to left center field to indicate the location of his next home run. The mighty Babe holds his bat across his shoulder, with one hand holding the small end of the bat. The bat is horizontal, and the distance...

A uniform crate with a mass of 16.2 kg rests on a floor with a coefficient of static friction equal to 0.571. The crate is a uniform cube with sides 1.21 m in length. what is the minimum height where the force F can be applied so that the crate begins to...

a 9.50-g bullet. moving horizontally with an initial speed vi , embeds itself in a 1.45-kg pendulum bob that is initially at rest. The length of the pendulum is L=0.745m. After the collision, the pendulum swings to one side and comes to rest when it has g...

The fundamental of an organ pipe that is closed at one end and open at the other end is 261.6 Hz ( middle C ). The second harmonic of an organ pipe that is open at both ends has the same frequency. What are the lengths of the pipe? I tried solving it and...

How do I determine the horizontal distance traveled by water passing through a hole of a punctured water bottle. You must use bernoulli's and Kinematics, and find delta x in term of h and y. ( y = the height of water inside the bottle , h = the height of...

a 35 g ice cube at 0.0 C is added to 110 g of water in a 62 g aluminium cup. The cup and the water have an initial temperature of 23 C . Find the equilibrium temperature of this system? in Celsius ,, I've been trying to solve this for 2 hours now , and I...

Determine the magnitude and direction of the total electric force on the +q charge by the +Q and -Q charges respectively. it should express and algebraic expression using Q,q,x,d and fundamental constants. -- I am trying to post a graph but it is not will...

I know that ,, but I don't think the will give this kind of stupid question to a first year college student. I only know that it is a center of mass equation !

Thanx ,, but I got something equals to 239.51 m/s .. and I don't think it is right .. I did it like this 1/2 ( 0.0095 + 1.45 ) sqrt ( 2*9.8*0.124) = 0.0095 vi

I got my mistake ,, thank you very much for the help :)

No I didn't get it right :S ,, I did it like this exactly ( 0.0095 + 1.45 ) sqrt ( 2*9.8*0.124) = 0.0095 vi

Thanks the answer was right, I related it to the small mass and it made sense ,, I submitted it , and it was right

I know how to speak Arabic, but I don't get your question , if you rephrase it , I may understand what you mean ;)

Solved it thank you

Thanx I will try it out

Thank you very much :D
