Lab 1 5
Work done weight height. From the question details provided im assuming that the block is being lifted up vertically at a constant velocity. 124 to 147 lbs. 10 98 5 490 joules. Work force and distance are related to each other. Where m mass. Imagine the following case.
How to calculate your optimal weight and height method 1. Work force and acceleration are the basic concepts of travel and distance calculations in physics. 119 to 142 lbs. Stack exchange network consists of 177 qa communities including stack overflow the largest most trusted online community for developers to learn share their knowledge and build their careers. Heavier work should generally be lower than elbow height so that it is possible to take advantage body weight and larger muscle groups of the torso. Lighter work such as precision work or inspection tasks that are visually intense should be higher so that you can see better.
Enter the required values know the unknown value of work or force or distance. Quetelet body mass index. G acceleration due to gravity. 673 views view 3 upvoters. Determine the work done by lamar in lifting. Thus the net force which can be found through the equation fma is 0.
Also note that when you lift a 1 lb weight upward by a distance of 5 ft the work performed is also 5 ft lbs. 148 to 193 lbs. 4 10 91 to 118 lbs. 4 11 94 to 123 lbs. When you apply a greater force the work done and the distance travelled is high and vice versa. So that should amount to not less than m g h 501018 900 joules.
5 97 to 127 lbs. 143 to 186 lbs. 1 the work you perform on the weight during the lift is thus the work you performed in lifting the 5 lb weight is 5 ft lbs. Knowing your body mass index can help you to steer clear of such unhealthy. Note that arm supports are often helpful in these situations. As the velocity is constant the acceleration is 0.
The quetelet index is useful in determining the amount of fat in your organism. If your height is lets say 180m then the total mechanical work would be the work done while lifting the suitcase plus some extra work due to the inefficiencies of the human body machinery internals.
