Question

5. A spring balance is used to weigh a fish. The combined mass of the fish and the pan is 1.50

kg. If the spring constant is 1200 N/m. What distance does the spring stretch?

Answer 1

• We know the formula

`\\ \rm\Rrightarrow x=(2mg)/(k)`

`\\ \rm\Rrightarrow x=(2(1.5)(9.8))/(1200)`

`\\ \rm\Rrightarrow x=(3(9.8))/(1200)`

`\\ \rm\Rrightarrow x=(9.8)/(400)`

`\\ \rm\Rrightarrow x=0.0245m`

2.45cm is distance
