A stuntman with a mass of 85.0 kg swings across a pool of water from a rope that is 10.0 m. At the bottom of the swing the stuntman's speed is 8 m/s. The rope's breaking strength is 1,000 N.

(a) Will the stuntman make it across the pool without falling in?

(b) What is the maximum speed (in m/s) that the stuntman can have at the bottom of the swing on this vine to safely swing across the river?

m/s

Step 1

(a)

No, the stuntman will not falling in, he crosses the pool of the river.

Step 2

(b)

According to the Newton’s law of motion, the acceleration of the stuntman is,

Substitute the values,
