Afisherman is using a very light fishing line that breaks when the tension exceeds 20n. he lifts a fish vertically out of the water with an upwards acceleration of 2 m/s^2. what is the largest mass of the fish for which the line will hold?

1.695 kg

Explanation:

maximum tension, T = 20 N

acceleration, a = 2 m/s^2

acceleration due to gravity, g = 9.8 m/s^2

Let the mass of fish is m.

Use Newton's second law

T - mg = ma

T = m (g + a)

20 = m (9.8 +2 )

m = 1.695 kg

Thus, the largest mass of the fish is 1.695 kg.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
