Rutherford discovered the nucleus of the atom by firing a particles at gold foil. an a particle has a charge of q = +2e and a mass of m = 6.64-10-27 kg. a gold nucleus has charge of q-+79e. you may ignore the motion of the gold nucleus in this problem +2e +79e suppose an α particles is traveling directly toward a gold nucleus. if the speed of the a particle is u = 1.9. 107 m/s when it is 1 m from the gold nucleus, how close to the gold nucleus will the a particle come before it stops and reverses direction?

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?
