In an arcade game a 0.099 kg disk is shot across a frictionless horizontal surface by compressing it against a spring and releasing it. If the spring has a spring constant of 244 N/m and is compressed from its equilibrium position by 4 cm, find the speed with which the disk slides across the surface. Answer in units of m/s.

The speed of disk is 1.98

Explanation:

Given:

Mass of kg

Spring constant

Compression of spring m

From energy conservation theorem,

Spring potential energy converted into kinetic energy,

Therefore, the speed of disk is 1.98

c

explanation:

i believe the answer is c and this is only worth 10 points you might wanna change it

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000
