Question
The video only states the distance=25m, time 1 min 15 sec and weight 97000 lbs
Video clip from 2009 World's Strongest Man competition-Plane Pull https: //www.youtube.com/watch?v-nlGDv607u9U Use the data from the video and assume that the plane's acceleration is constant. Calculate the net force acting on the plane. One of the announcers says: "It's hard to imagine how a human can pull such a colossal object." Use Newton's laws to explain how a human can pull such a colossal object. (44 tonnes = 44,000 kg. Weight almostequalto 97,000 lbs.)Explanation / Answer
D = 25m
time t = 1m 15s = 75s
Weight w = 97000 lbs = 431650 N
mass m = w/g = 431650/9.81 = 44001 kg
We know, F = ma
Now, a = v/t = (D/t)/t = D/t^2
So,
F = mD/t^2 = (44001)(25)/75)^2 = 195.56 N
