A 10-kg shopping cart is rolling down the aisle at a rate of 2 m/s when it collides with a 20-kg shopping cart loaded with food that’s traveling in the same direction but at a rate of 1 m/s. If the first cart slows to 1.2 m/s after the collision, what is the speed of the 20-kg cart after the collision?

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
