A crane is lifting a 500-kg object at a constant speed of 0.5 m/s. What is the power output of the crane

The power output is 2450 W

Explanation:

Give;

mass of the object, m = 500 kg

velocity of the object, v = 0.5 m/s

The power output is given  by the following equation;

P = F x V

Where;

P is the output power

F is the applied force

P = (mg) x v

P = ( 500 x 9.8) x 0.5

P = 2450 W

Therefore, the  power output is 2450 W

which piece of furniture will have the most inertia and give the furniture movers the most difficulty in moving?  

answer

a 75kg dining table

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
