It takes the elevator in a skyscraper 3.6 s to reach its cruising speed of 10 m/s. A 69 kg passenger gets aboard on the ground floor.
1.What is the passenger's weight before the elevator starts moving?
2.What is the passenger's weight while the elevator is speeding up?
3.What is the passenger's weight after the elevator reaches its cruising speed?

the passenger's weight is ALWAYS mass x acceleration.

Can you work out the acceleration at all 3 stages?

The mass of the person is the same for all 3.

How do i find the acceleration?Is it 9.8m/s^2?
and do i need to convert kg into g?
