Answer:
The two skaters will move with a common speed of 1.19 m/s.
Explanation:
Given that,
Mass of Alex,
Initial velocity of Alex,
Mass of Barbara,
Initial velocity of Barbara,
After the collision, the two skaters move together at a common velocity. Let V is the common velocity. Using the conservation of momentum as :
Magnitude of final velocity:
So, the two skaters will move with a common speed of 1.19 m/s.
Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton. meter (N. ... One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m

Answer:
force= mass x acceleration
3000 N = m x 15
m= 3000/15
m=200 kg
