In an arcade game a 0.14 kg disk is shot acrossa frictionless horizontal surface by compress-ing it against a spring and releasing it.155 n/m and is compressed from its equi-librium position by 4 cm, find the speed withwhich the disk slides across the surface.1. 4.64532. 2.037063. 3.691154. 4.367985. 1.916356. 1.330957. 1.985198. 1.45289. 3.3657110. 2.3719

The speed with which the disk slides across the surface is 1.33095 m/s.

Explanation:

Given that,

Mass of disk = 0.14 kg

Spring constant = 155 N/m

Length = 4 cm

We need to calculate the speed

Using energy conservation

Where, k = spring constant

x = compressed length

m = mass of the disc

Put the value into the formula

Hence, The speed with which the disk slides across the surface is 1.33095 m/s.

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

im doing peak rn so sry if its wrong
