Alight horizontal spring has a spring constant of 105 n/m. a 2.00 kg block is pressed against one end of the spring, compressing the spring 0.100 m. after the block is released, the block moves 0.250 m to the right before coming to rest. what is the coefficient of kinetic friction between the horizontal surface and the block?

Coefficient of friction,

Explanation:

Given that,

Spring constant of the spring, k = 105 N/m

Mass of the block, m = 2 kg

The compression in the spring, x = 0.1 m

Let is the coefficient of kinetic friction between the horizontal surface and the block. The frictional force is balanced by the restoring force in the spring such that,

So, the coefficient of kinetic friction between the horizontal surface and the block is 0.535. Hence, this is the required solution.

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).
