a) when the lift accelerates upwards at 0.3m/s^2

b) when the lift travels at constant speed

c) when the lift accelerates downwards at 0.3m/s^2

For (a) is it T- W-w= ( M+m) a

Where T is tension of the cable, W is the weight of the lift and w is the weight of the mass.

I don't know how to calculate (b) and (c)
