Answer:
m = 84.66 kg
Explanation:
given,
tightrope walker across = 30 m
displacement vertically downward = 1 m
force at center = 6250 N
m = 84.66 kg
hence, the mass of the tightrope walker m = 84.66 kg
100J/20s= 5 joules per second
Or 5 watts
your answer is going to be all of the above
Kg are weight, m are length lol soooooo
