An adventurous archeologist (m = 80.5 kg) tries to cross a river by swinging from a vine. the vine is 11.0 m long, and his speed at the bottom of the swing is 7.80 m/s. the archeologist doesn't know that the vine has a breaking strength of 1,000 n. does he make it safely across the river without falling in?

He made it, he across safely the river without falling ing.

Explanation:

Vt= 7.8 m/s

r= 11m

m= 80.5 kg

Vt= ω * r

ω= 0.71 rad/s

ac= ω² * r

ac= 5.54 m/s²

F= m * ac

F= 445.97 N  < 1,000 N

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
