An elevator of mass M with a person of mass m is moving upward with uniform velocity `vecv`. What is the power delivered by the elevator?

A

(I)(i)(S)

B

(II)(i)`(R)`

C

(III)(iii)(P)

D

(IV)(iii)(Q)

Text Solution

Verified by Experts

The correct Answer is:
B, C
For elevator acceleration `1.5m//s^(2)`, tension is cord 2 and cord 3 is zero
So, `T_(1)-150=(15)(1.5)`
`implies` Tension in cord `1, T_(1)=172.5N`
