Question 1
A person weighing 0.70 kN rides in an elevator that has an upward acceleration of 1.5 m/s2. What is the magnitude of the force of the elevator floor on the person?
◦
0.11 kN
◦
0.81 kN
◦
0.70 kN
◦
0.59 kN
◦
0.64 kN
Question 2
Aline and Charlie are arguing as to whether or not it is possible in principle for an elevator to have an acceleration of magnitude greater than g. In the course of their discussion they come up with the statements below. Which one is correct?
◦
No, because once
reaches
g, the elevator is in free fall.
◦
No, because an acceleration greater than g is not possible.
◦
Yes, because it can reach an acceleration greater than g when the cable breaks.
◦
Yes, because it can reach an acceleration greater than g if the motor is strong enough.
◦
No, because it cannot exceed its terminal acceleration.
