Rodney’s mass is 84.0 kg , and he is standing on a bathroom scale in an elevator starting from rest the elevator accelerates upward at 2.25 m/s^2 for 3.01 s and then continues at a constant speed , is scale reading during acceleration greater than , equal to or less than the scale reading when the elevator is at rest ?

any one of the statements could be an accurate comparison. but the statement that would define the correct choice and seal the deal is not even on the list:

"the visibilities of vector-x and vector-y in the drawing provided with the question are identical and nonexistent."

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
