Amovie stunt performer is filming a scene where he swings across a river on a vine. the safety crew must use a vine with enough strength so that it doesn't break while swinging. the stunt performer's mass is 80.0 kg, the vine is 11.5 m long, and the speed of the stunt performer at the bottom of the swing has been determined to be 7.00 m/s. what is the minimum tension force (in n) the vine must be able to support without breaking?

1125.66956 N

Explanation:

m = Mass of stunt performer

g = Acceleration due to gravity = 9.81 m/s²

v = Velocity of the swing = 7 m/s

T = Tension

r = Radius of the swing = Length of vine = 11.5 m

From the free body diagram

The minimum tension force the vine must be able to support without breaking is 1125.66956 N

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate
