Question

on the magnet et Angel rivacy & S. Need Help? A 67-kg man on a scale in an notes that as the elevator rises, the scale reads 828 N. What is the of the me? upward Need Help? Read It 5. A 4.8-g bullet leaves the muzzle of a rifle with a speed of 326 m/s. What force (a traveling down the 0.83-m-long barrel of the rifle? Need Help? Two forces are applied to a car in an effort to move it, as shown in the figure below. (Let F 43S N and 2 373 N. Assume up and to the right are in the positive directions.) l0*

Explanation / Answer

4] The net force on the person in the elevator is:

R - mg = ma

=> R = m[g + a] = 828

=> 67[9.8 + a] = 828

=> a = 2.5582 m/s2.

this is the acceleration of the elevator in the upwards direction.
