4. One day Ali decided to weigh himself in an elevator on a bathroom
scale calibrated in newtons. He did this while the elevator was
stopped and again while it was moving. His mass is 80 kg
the scale read 784 N while the elevator was stationary. Next he
weighed himself while the elevator moved upwards at a constant
speed of 2 m/s. What was his weight at this time?
A. 624 N
B. 944 N
C. 784 N
D. 160 N

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
