Questur 12 This question contains multiple parts. Make sure to read all the instructions and answer each part. Tarzan plans to cross a gorge by swinging in an arc from a hanging vine. His massis 87.3kg and the vine is 4.09m long. Image size: ML Max (1 points) Parta If his arms are capable of exerting a force of 1400 N on the rope, what is the maximum speed he can tolerate at the lowest point of his swing? Please enter a numerical answer below. Accepted formats are numbers or "e" based scientific notation e.g. 0.23, -2, 126, 5.23e-8 5.05 m/s Xaywer Your actual answer was 5 which differs from the answer above by a small rounding error or significant figures.

need help with Part B

Answer 1

b)

forces along vertical

T cos x = mg

T cos 40 = 87.3* 9.8

T = 1.117* 10^3 N

Note: previous answer is also correct but typing format may cause error.
