Jake the deliveryman pushes a box up a ramp, exerting a force of 350 N. He walks on the ramp, pushing the box for 25.0 m. If the box
has a mass of 50.0 kg, what is the height of
the ramp and the angle it makes with the
horizontal? Ignore friction.

The electric field inside a cell membrane is 8.0mn/c. what's the force on a singly charged ion in this field?

Two cans on a sunny window one black and the other white construct and explanation of the effect of sun will have on both cans over a two hour period?

Momentum lab this lab uses a phet simulation. navigate to the phet momentum simulation. if you don’t see the image below when you click on the link, then you need to either enable adobe flash (click on the puzzle piece on your screen) or you need to install adobe flash (this is a free program). change the vectors to be momentum vectors only. they are yellow. make the mass of both balls the same. hit play and notice what happens to the momentum vectors before and after the collision. you might want to play the sim multiple times. click on restart or return balls to start over. to see numbers, check the show values box (inside the green box). red’s momentum vector before the collision is green’s momentum vector after the collision. question 1 options: shorter than longer than equal to question 2 (1 point) saved since green bounces off red, this must be an collision. question 2 options: explosion inelastic elastic question 3 (1 point) red transfers of its momentum to green during the collision. question 3 options: little all most none question 4 (4 points) why does red transfer all its momentum to green? back up your answer with information from the simulation. write at least 2 sentences.
