Answer:NOPE you need more

Step-by-step explanation:

The power required to lift a weight depends on the force needed and the speed at which the weight is lifted. The force required to lift a weight is given by the equation F = m * g, where m is the mass of the object and g is the acceleration due to gravity (approximately 9.81 m/s² on Earth).

For example, if a 1000 kg weight is lifted 10 m in 10 seconds, the work done can be calculated as W = (1000 kg) * (9.81 m/s²) * (10 m) = 98100 J (Joules). The power required is work done per unit time P = (98100 J) / (10 s) = 9810 W (Watts), which is approximately 9.8 kW¹.

In terms of horsepower, since 1 horsepower is approximately equal to 746 Watts¹, the power required would be about 13.15 horsepower. So, it does not require 100 horsepower to lift a 1000 kg weight from the ground under these conditions. However, these calculations assume ideal conditions and do not take into account factors such as air resistance or mechanical inefficiencies. In real-world applications, more power might be needed.
