A flight attendant pulls her 70.10 n flight bag a distance, Ask an Expert

Academics

Q1. You have a mass of 59 kg and are on a 56-degree slope hanging on to a cord with a breaking strength of 220 newtons. What must be the coefficient of static friction to 2 decimal places between you and the surface for you to be saved from the fire?

Q2. A flight attendant pulls her 70.10 N flight bag a distance of 258 m along a level airport floor at a constant speed. The force she exerts is 36.30 N at an angle of 52.0° above the horizontal.

(a) Find out work she does on the flight bag.

(b) Find out work done by the force of friction on the flight bag.
