A car with mass m v0 is moving at low speed. If this has a wind resistance proportional to the speed of the car, Fd = kv, calculate the distance and time traveled until the speed of the car reaches 0.5v0. Assume that no other friction is applied to the car

When can a theory be modified if a new type of technology allows for new observations that raise new questions? a-immediately, while the questions about the theory are being asked b-after new hypotheses related to the theory are tested in experiments c-only after the new observations disprove all parts of the theory d-while scientists begin to think about how the theory could improve
