A 54.0 kg ice skater is moving at 3.98 m/s when she grabs the loose end of a rope, the opposite end of which is tied to a pole. She then moves in a circle of radius 0.802 m around the pole. (a) Determine the force exerted by the horizontal rope on her arms. N
(b) What is the ratio of this force to her weight?(force from part a / her weight)

(a) force is 1066.56N

Explanation:

(a) MV²/R

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
