A skater moves at 0.8 m/s towards the north end of the rink. If her momentum is 38 kg m/s north, what is her mass?

Respuesta :

Answer:

m = 47.5 Kg

Explanation:

given,

speed of skater toward north, v = 0.8 m/s

momentum of the skater in north, P = 38 Kg.m/s

mass of the skater = ?

we now,

Momentum is equal to the product of mass and velocity

P = m x v

38 = m x 0.8

[tex]m = \dfrac{38}{0.8}[/tex]

m = 47.5 Kg

hence, mass of the skater is equal to 47.5 Kg.
