Answer:
I'd say 85km sorry if wrong
Explanation:
Two forces:gravity and the support force that apposes it
Answer:
T = 228.3N
Explanation:
We are given:
w = 130N
r = 4.0m
We take g = 10
Therefore:
w = m×g
130 = m × 10
m = 130/10
m = 10
At the lowest point,we use the equation:
;
Since we are asked to find tension T, we now have:
Therefore, substituting figures in the equation, we have:
;
T = 228.3N
The tension in the rope is 228.3N
