Question

Problem 34.56 Part A You've recently read about a chemical laser that generates a 20.0-cm- What speed would such a block have if pushed horizontally 96.0 m along a frictionless track by such a laser? Express your answer with the appropriate units. diameter, 22.0 MW laser beam. One day, after physics class, you start to wonder if you could use the radiation pressure from this laser beam to launch small payloads into orbit. To see if this might be feasible, you do a quick calculation of the acceleration of a 20.0-cm-diameter, 98.0 kg, perfectly absorbing block alue Units Submit My Answers Give Up

Explanation / Answer

vf = sqrt [2 a * delta x] = sqrt [2 pR A * delta x / m]

= sqrt [2 P * delta x / m c]

= sqrt [2 * 22 * 106 * 96.0 / 98 * 3 * 108]

= 0.379 m/s
