Two ice skaters approach each other at right angles. skater a has a mass of 32.7 kg and travels in the x direction at 2.3 m/s. skater b has a mass of 93.3 kg and is moving in the y direction at 1.51 m/s. they collide and cling together. find the final speed of the couple. answer in units of m/s.

Final speed, v = 1.25 m/s

Explanation:

Given that,

Mass of skater A,

Initial speed of skater A, (x axis)

Mass of skater B,

Initial speed of skater B, (y axis)

It is mentioned that the two skaters collide and cling together. It is case of inelastic collision in which momentum remains conserved. Let V is the final speed of the couple. It is given by :

So, the final speed of the couple is 1.25 m/s. Hence, this is the required solution.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the inner core.

good luck: )
