Question
A Skier with a mass of 65.0 kg. Including equipment, starts from rest and accelerates down a slope. The slope is 27.0 m higher at the top than the bottom. The work done on the skier by the kinetic friction is 1.20 x 10^4 J.
How would I determine the Gravitational potential energy...
What formula would I use to solve for a and b?
A 0.20-kg ball is held at rest 2.2 m above the ground, and then it is dropped. Apply the law of conservation of energy to determine the ball's speed after it has fallen (a) 1.1 m and (b) 2.2 m. Ignore air resistance.
Answers
(a) 4.6 m/s
(b)...
How would I solve this equation:
3(x-3) + 4x+7= 5x-3
And How would I solve these Quadratic Equation:
x^2 + 7x + 12 = 0
3x^2 - 10x + 8 = 0
8y^2 + 18y = 5 = 0
Thanks.
How would I solve these equation:
(3 3/8) to the power of -1
3X / X-1 + 4 = X / X+1
5 / X+2 + X(X+3) / X (Square) - 4
I been really stuck on these.
Thanks
