An elevator cab is pulled upward by a cable. The cab and its single occupant have a combined mass of 1820 kg. When that occupant drops a coin, its acceleration relative to the cab is 8.50 m/s2 downward. What is the tension in the cable?

Explanation:

Given

combined mass of cab and occupant is

acceleration of coin w.r.t cab is

we can write

where =acceleration of coin w.r.t cab

=acceleration of cab w.r.t ground

=acceleration of coin w.r.t ground

thus

i.e. elevator is moving downward with an acceleration of

Therefore

the answer is b

explanation:

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
