A fish (8 kg) is being yanked vertically upward out of the water and the fishing line breaks. If the line is rated to a maximum

Answer:

The minimum acceleration of the fish is 10.2 m/s²

Explanation:

The force on string is:

F = 8 * 9.8 = 78.4 N

According the Newton second law:

T - W = ma

Where T = tension of the string = 160 N

W = weight of the fish = 78.4 N

m = mass of the fish = 8 kg

a = acceleration of the fish = ?

Clearing a:

a = (T- W)/m = (160 - 78.4)/8 = 10.2 m/s²

Answer:

Explanation:

Given:

Mass of the fish, 8 kg

Tension of the line, F = 160 N

Tension of the line, F + normal force = 0

Normal force, Fn = Mass × acceleration

Acceleration = force/mass

= 160/8

= 20 m/s^2

Minimum acceleration = 20 m/s^2

When an 80.0-kg man stands on a pogo stick, the spring is compressed 0.120 m. (a) What is the force constant of the spring? (b)
Nimfa-mama [501]

Answer:

a.6533.333 N/m

b.Yes,the spring will be compressed more when the person hops down the road .

Explanation:

Mass of man=80 kg

Spring compressed by x=0.12 m

a.We have to find the force constant of the spring.

Spring constant=k=\frac{F}{x}=\frac{mg}{x}

g=9.8m/s^2

Using the formula

Spring constant,k=\frac{80\times 9.8}{0.12}N/m

Spring constant=k=6533.33 N/s

b.The spring will be compressed more when the person hops down the road because when the person hops down then the kinetic energy of person will be converted into potential energy during the road hit.
