Answer:

• Angular velocity is 2 m/s

• Centripetal force is 96 N

Explanation:

For angular velocity:

{ \rm{v =  \omega r}}

  • v is velocity
  • w is angular velocity
  • r is radius

{ \rm{ \omega =  \frac{v}{r} }} \\  \\ { \rm{ \omega =  \frac{12}{6} }} \\  \\  { \boxed{ \rm{ \omega = 2 \:  {ms}^{ - 1} }}}

For the centripetal force:

{ \rm{force = m { \omega}^{2}r }} \\  \\ { \rm{force = (4 \times  {2}^{2}  \times 6)}} \\  \\ { \rm{force = 96 \: newtons}}

It took 1700 J of work to stretch a spring from its natural length of 2m to a length of 5m. Find the spring's force constant.
Alenkasestr [34]
The work to stretch a spring from its rest position is

               (1/2) (spring constant) (distance of the stretch)²

           E = 1/2 k x² .

You said it takes 1700 joules to stretch the spring 3 meters from its rest position, so we can write

                 1700 joules  =  1/2 k (3m)²

1 joule = 1 newton-meter

                 1700 N-m =  1/2 k  (3m)²

Multiply each side by 2:   3400 N-m  =  k · 9m²   

Divide each side by  9m²     k  =  3400 N-m / 9m²

                                                   =  (377 and 7/9)   newton per meter
