Answer: sq. root of .735
Explanation:
multiply two on both sides.
(2) *2,94 = (0,200 * v^2) (2)
588 = 0400 * 2v^2
divide by 400 on both sides
1.47 = 2v^2
divide by 2 on both sides
.735 = v^2
take square root of both sides
or .85732141
Answer:
v' = 2.4 m/s
Explanation:
Given that,
Mass of one skater, m = 60 kg
Mass of the other's skater, m' = 60 kg
The two skaters push off each other. After the push, the smaller skater has a velocity of 3.0 m/s.
When there is no external force acting on a system, the momentum remains conserved. It means initial momentum is equal to the final momentum. Let v' is the velocity of the larger skater.
mv = m'v'
So, the velocity of the larger skater is 2.4 m/s.
