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.

explanation:

v=uf/(u-f)

another example of kinetic energy would be,

kinetic energy   >     moving energy
