In an arcade game, a 1.12 kg disk is shot across a frictionless horizontal surface by being compressed against a spring and then released. If the spring has a spring constant of 230 N/m and is compressed from the equilibrium position by 6.0 cm, what is the magnitude of the spring force ont he disk at the moment it is released?

The magnitude of the spring force on the disk at the moment it is released is 13.8 N

Explanation:

Given;

Mass of the disk, m = 1.12 kg

spring constant, k = 230 N/m

extension produced in the spring, x = 6.0 cm

According to Hook's law, the force applied to an elastic material is directly proportional to the extension produced.

F = kx

Where;

K is the spring constant

x is the extension of the spring

F = 230 x 0.06

F = 13.8 N

Therefore, the magnitude of the spring force on the disk at the moment it is released is 13.8 N

b mirrors submit a iisner? e. for which optical devices does d sometimes have a positive value? o a a and b o b. a and c o c. b and d 0 d. b and cb

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
