what power is required to lift a 5.0 kg mass vertically with a constant speed of 3.0m/s

Question

anonymous · Answer

i think, you can always easily solve units to get a formula
P=E/t


P=Watt=J/s

J=N.m

     N=kg.m/s2

J=kg.m2/s2

P=kg.m2/s3
 =kg.m/s2  x   m/s
 =

hence you get formula for P

you can figure out the formula from here,
now what you need to know is what F you should apply to carryout a vertical motion.

anonymous · Answer

$$P=Fv$$
P=Power
F=Force
v=velocity

anonymous · Answer

in this case,  the force is the weight of the object which you can find by multiplying the mass and the acceleration due to gravity (which is 9.81 approx.. 10)
$$F=mg$$
