Question 46521:
Good evening, i have this problem about physic. i can not work out .Please would u work for me ?
Potential gravitational enery( defined as 'mass' mulitiplied by 'gravitational acceleration' by "height" - or mgh ) is one form of energy, and and kinetic energy ( defined as half the product of 'mass' mulitiply by 'velocity squared' - or mv2/2 ) is another. Assuming the conservation of energy ( and that there are no resisting forces ), from what height would a car have to fall to gain the kinetic energy it it would have when going at 60 kilometers per hour?
Please solve this problem for me.
Yours faithful student Emma Mode

Question 47317: please help me solve the problem,
What is the center of the hyperbola?
(x-2)^2/9-(y-5)^2/4=1
is it (3,2) 0r (9,4) or (2,5)
i tryed grafting this but it doesn't give any center when i graft it where did i go wrong?
