Question

What is the power involved in lifting a 1.0-kg object 1.0 m in 1.0 s??

Answer 1

The power involved in lifting a 1.0-kg object 1.0 m in 1.0 s is 9.8 watts.

Step-by-step explanation:

The power involved in lifting a 1.0-kg object 1.0 m in 1.0 s can be calculated using the formula: power = work/time.

Work is equal to the force applied multiplied by the distance moved. In this case, the force is equal to the weight of the object, which is the mass multiplied by the acceleration due to gravity. So the force = (1.0 kg)(9.8 m/s²) = 9.8 N.

Therefore, the work done is (9.8 N)(1.0 m) = 9.8 J.

Finally, the power involved is 9.8 J / 1.0 s = 9.8 W.

Answer 2

Mass = 1kg
Distance = 1m
Time = 1s
Force= Mass x Acceleration due to graviy
= 1 x 9.8 = 9.8
Velocity = Distance / time
= 1 / 1 =1m/s
Power = Force x velocity
= 9.8 x 1 = 9.8 W
