A750 g air-track glider attached to a spring with spring constant 14.0 n/m is sitting at rest on a frictionless air track. a 200 g glider is pushed toward it from the far end of the track at a speed of 170 cm/s . it collides with and sticks to the 750 g glider. what are the amplitude and period of the subsequent oscillations?

the amplitude of  the subsequent oscillations is 0.11  m

the period of the subsequent oscillations is 1.94 s

Explanation:

given Information:

the mass of air-track glider, = 750 g = 0.75 kg

spring constant, k = 13.0 N/m

the mass of glider, = 200 g = 0.2 kg

the speed of glider,   = 170 cm/s = 1.7 m/s

the amplitude of  the subsequent oscillations is A = 0.11  m

according to mechanical enery equation, we have

where

A is the amplitude and   is the final speed.

to find , we can use momentum conservation lwa, where the initial momentum is equal to the final momentum.

= 0, thus

(0.75+0.2) = (0.75)(0)+(0.2)(1.7)

0.95 = 0.34

= 0.36 m/s

Now we can calculate the amplitude

A = 0.11  m

the period of the subsequent oscillations is T = 1.94 s

the equation for period is

T = 2π

T = 2π

T = 1.94 s

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

ill do it for 100, also this isnt 80 its 40
