Two carts with masses of 17.5 kg and 1.5 kg, respectively, move in opposite directions on a frictionless horizontal track with speeds of 8.0 m/s and 4.0 m/s, respectively. The carts stick together after colliding head-on. Find the final speed of the two carts.

V = 6.97m/s

Explanation:

Using equation of collision;

m1u1 + m2u2= v( m1 + m2)

V= m1u1 + m2u2/m1 + m2

Since the other object is moving in an opposite direction it momentum becomes negative

So we have

V=m1u1+(-m2u2)/m1 + m2

Impute the data

V = 17.3×8 + (-1.5×4)/17.5+1.5

V= 138.4 - 6/19

V= 132.4/19

V= 6.97m/s.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

h o h o hope you have a merry christmas!
