And are separated by 2.00 nm. Neglecting any motion of the much more massive proton, what is the minimum (a) kinetic energy and (b) speed with which the electron must be projected at so it reaches a point a distance of 12.0 nm from the proton? Assume the elec- tron’s velocity is directed radially away from the proton. (c) How far will the electron travel away from the proton if it has twice that initial kinetic energy?

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)
