Their velocity afterwards is 2.88 m/s east
Explanation:
We can solve this problem by using the law of conservation of momentum. In fact, for an isolated system (= no external force), the total momentum must be conserved before and after the collision. So we can write:
where: in this case:
is the mass of the first player
is the initial velocity of the first player (choosing east as positive direction)
is the mass of the second player
is the initial velocity of the second player
is their combined velocity afterwards
Solving for v, we find:
And the sign is positive, so the direction is east.

Answer:
Explanation:
Given that,
The length of tension wire is 10m
L = 10m
It caries a current of 10A
I = 10A
The current is perpendicular to the magnetic field
B = 5.5 × x10⁻⁵ T.
Then, θ = 90°
The magnetic force that act on the line is?
F = i(L × B)
L × B = LB Sinθ
Where
I is the current
L is the length of the wire
B is the magnetic field
θ is the angle between the field and the direction of the length.
Then,
F = I × L × B × Sinθ
F = 10 × 10 × 5.5 × x10⁻⁵ × Sin 90
F = 5.5 × x10⁻³ N
Then, the magnetic force experience on the line is 5.5 × x10⁻³N
