how did you obtain those answers? I don't think they're correct.

Homework Statement A light spring of force constant 3.75 N/m is compressed by 8.00 cm and held between a 0.250 kg block on the left and a 0.490 kg block on the right. Both blocks are at rest on a horizontal surface. The blocks are released simultaneously so that the spring tends to push them...

I forgot to post the picture. Here it is:

Homework Statement An inclined plane of angle θ = 20.0° has a spring of force constant k = 455 N/m fastened securely at the bottom so that the spring is parallel to the surface as shown in the figure below. A block of mass m = 2.71 kg is placed on the plane at a distance d = 0.330 m from the...

A snow-covered ski slope makes an angle of θslope = 29.0° with the horizontal. When a ski jumper plummets onto the hill, a parcel of splashed snow is thrown up to a maximum displacement of 1.70 m at θsnow = 19.0° from the vertical in the uphill direction as shown in the figure below. (a)...

Oh I got it thanks!

In a game of American football, a quarterback takes the ball from the line of scrimmage, runs backward for 10.5 yards, and then runs sideways parallel to the line of scrimmage for 15.0 yards. At this point, he throws a forward pass 55.0 yards straight downfield perpendicular to the line of...

What about a http://www.google.com/search?hl=en&source=hp&biw=1066&bih=590&q=demagnetizer&aq=0s&aqi=g-s1g1g-s8&aql=&oq=demagni", would that work?

For instance, let's say that i have a piece of metal (ie paperclip, coin, etc) that sticks to a magnet. Is there a way to remove its magnetic properties, so that it can't stick to metal? Using curie point to demagnetize is only temporary. Is there a way to permanently demagnitize a magnetic...
