Answer:

Bruces mass is 63kg

Explanation:

⟼ΔP=P

⟼m1v1=m2v2

⟼90(7)=m2(10)

⟼10m2=630

⟼m2= 630/10

⟼m2=63kg

\\ \sf\longmapsto \Delta P=P

\\ \sf\longmapsto m1v1=m2v2

\\ \sf\longmapsto 90(7)=m2(10)

\\ \sf\longmapsto 10m2=630

\\ \sf\longmapsto m2=\dfrac{630}{10}

\\ \sf\longmapsto m2=63kg

Bruces mass is 63kg

A small ball is attached to one end of a spring that has an un- strained length of 0.200 m. The spring is held by the other end,
masya89 [10]

Answer:

\Delta x=0.002287\ m=2.287\ mm

Explanation:

Given:

  • un-stretched length of the spring, l=0.2\ m
  • speed of revolution of the ball in horizontal plane, v=3\ m.s^{-1}
  • length stretch during the motion, \Delta l=0.01\ m

<u>Now the radius of revolution of the ball:</u>

r=l+\Delta l

r=0.2+0.01

r=0.21\ m

<u>Now in this case the centrifugal force is equal to the spring force:</u>

F_c=F_s

m.\frac{v^2}{r} =k.\Delta l

where:

m = mass of the ball

k = spring constant

m\times \frac{3^2}{0.21} =k\times 0.01

k=(4285.714\times m)\ N.m^{-1}

<u>Now the extension in the spring upon hanging the ball motionless:</u>

m.g=k.\Delta x

9.8\times m=(4285.714\times m)\times \Delta x

\Delta x=0.002287\ m=2.287\ mm
