Answer to Question #183525 in Physics for Caitlin

Question

1. Inside an elevator, a 63.0 kg student stands on a bathroom spring scale that displays its readings in Newtons.

A) What will the scale read if the elevator accelerates upward at 1.50 m/s2?

B)What magnitude and direction of acceleration would be needed in order to produce a scale reading of 542.0 N?

C) Under what two types of elevator motion would the scale accurately display the student’s weight?

Question 2. A bullet of mass 6.45 g is fired from a 66.0 cm-long rifle barrel at 237 m/s. The mass of the rifle is 4.50 kg. Determine the acceleration of the bullet as well as the recoil acceleration of the rifle.
