This may not be the best place to ask, but anyways, in class we are doing an independent project. We need to analyse a technological device that uses the properties of gravitational, electrical, and/or magnetic fields (eg. MRI machine, particle accelerator, zero gravity experiments), and explain...

Alright so: 5.6448 + 11.76x = (0.5)(124)(x^2) 5.6448 + 11.76x = 62x^2 62x^2 - 11.76x - 5.6448 = 0 Then I use quadratic formula and x comes out to be: x = 0.411 m Is that right? :)

I don't really follow. What equation do you suggest I use?

A 1.2 kilogram block is dropped from 0.48m above a spring in equilibrium. The force constant for the spring is 124 N/m. Calculate the maximum compression in the spring. m = 1.2 kg h = 0.48 + x k = 124 N/m x = ? Ep = mgh Ep = (1.2)(9.8)(0.48 + x) Ep = 11.76(0.48 + x) Ep = 5.6448...

Haha, embarrassingly simple. Thank you!

So the answer would be C then? :)

A puck has a velocity of 3i –4j m/s and a mass of 20 kilograms. What is the momentum of the puck? A. 100 Ns B. 60i – 4j Ns C. 60i – 80j Ns D. 23i – 24j Ns Alright, so I calculated the velocity from the resultant vector to be 5 m/s. So: p = mv p = 20 kg x 5 m/s p = 100 Ns...
