What is the magnitude of the approximate average force exerted by the ground on your feet during the time when your knees are bending? (The force of the Earth is only = 539 N; you notice the unusually big force on your feet.)

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

total distance/total time

(85 + 82)/(5+3)

167/8
