Agroup of ten friends, each of mass 50kg, want to test the strength of a trampoline. at their highest jump, each friend is 2m above the trampoline. they all land on the trampoline at the same time and decelerate at a constant rate to a point of zero velocity over a period of 0.5s. the trampoline has a threshold of 5000n, above which it breaks. do the friends succeed in breaking their trampoline?
neglect air resistance and the distance the trampoline sags as a result of the friends landing.
\(\displaystyle g = 10\frac{m}{s^2}\)
possible answers:
a. no; they exert a force of \(\displaystyle 4691n\)
b. yes; they exert a force of \(\displaystyle 6325n\)
c. yes; they exert a force of \(\displaystyle 7149n\)
d. no; they exert a force of \(\displaystyle 4967n\)
