Ahockey puck is given an initial speed of 30 m/s on a frozen pond. the puck remains on the ice and slides 104 m before coming to rest. the acceleration of gravity is 9.8 m/s 2 . what is the coefficient of friction between the puck and the ice?

Explanation:

t = Time taken

u = Initial velocity of puck = 30 m/s

v = Final velocity of puck = 0

s = Displacement of the puck = 104 m

a = Acceleration

g = Acceleration due to gravity = 9.8 m/s²

= Coefficient of friction

Equation of motion

Coefficient of friction between the puck and the ice is 0.44152

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
