!!Urgent Help, Please! I have been stuck on this a while!!

Consider the belt drive where shaft A is being driven by a motor at a
constant speed and a constant torque. It is observed that the 10-kg weight
is being lifted at a constant rate of 2 m/s. Also, it is known that the belt drive
is 95% efficient.
a) What is the power being delivered by the motor?
b) What is the torque being delivered by the motor?
c) What is the RPM of the motor?

I believe I have solved for power where P=Power, v=velocity, m=mass, and g=gravity.$$P=mgv$$ $$P=(10)(9.8)(2)=196watts$$
