Friend as in the guy that just climed in my window and answered that question i wasnt tlaking about you.

F=md/s^2 rerange it s^2 = md/F Square root it... that what my friend says lol...

So in english I am wrong and what i said won't work?

lets leave out everything we have done so far at rest what is Fn? Fn=mg so his normal force is (47)(9.8) or 460.6N now "if the rider is to feel twice as heavy as he does when at rest?" if that's how much he feels at rest how does he wieght is that's doubled?

Confused :P i thought about it and now I am confused. Considering the wieght of the perosn is (47)(9.8) = wieght to get twice the wieght or 2(wieght)= (47)(9.8)(2) since multiplication is culmative or the order don't matter we can say eithier their mass or 9.8 or gravity has doubled. there mass...

Problem 1 A 12.0 kg shopping cart rolls due south at 1.50 m/s . After striking the bumper of a car, it travels at 0.80 m/s, 30° E of S. What is the magnitude of the change in momentum sustained by the shopping cart? a drew a free body diagram used the formula Pyo + Py1 = P'yo + P'y1 and Pxo +...

Thanks thats simple enough the t part for how long the force was acting... :P ill just solve it with momentum.

A stationary object explodes into two fragments. A 4.0 kg fragment moves westward at 3.0 m/s. What are the speed and kinetic energy of the remaining 2.0 kg fragment? why can't i assume the kinect enegery of each object is the same?I loked at it and assumed 1/2mv^2 for object 1 should equal...
