Question

A student, who weighs 770N, is standing on a bathroom scale and riding an elevator that is moving downwards with a speed that is increasing at a rate of 3.1m/s^2. How many forces are acting on the student? What is the student's mass? kg What is the net force on the student? N Which force does the scale read? normal force What value does the scale read? N

Step 1

There are two main forces acting on the student: the force of gravity (weight) pulling the student downwards, and the normal force exerted by the scale upwards against the student. The weight is given as 70N. Show more…
