Answer:
I'm not 100% sure, but I think the answer would be the first one because there's a force pushing the object in every direction, so they would cancel eachother out and make the object stay in the same place.

Answer:
Positions in Hockey: 6 players for each team on the ice
1 Goalie – the player in the goal who tries to stop the puck from going in the net.
1 Center – plays in between the two wings and is usually the best passer on the team
2 Wings – offensive players who plays on both sides of the center. They are usually goal scorers
2 Defensemen – main job is to play defense and help defend the goal
Passing Cues
1. Stick blade faces target
2. Puck in center of blade
3. Transfer weight rear to front as you pass
4. Use wrist movement to drive the puck
5. Follow through at target
Receiving Cues:
1. athletic position
2. catch puck with middle of blade and control
3. slow the puck when it contacts the stick by giving with it

Answer:
K_a = 8,111 J
Explanation:
This is a collision exercise, let's define the system as formed by the two particles A and B, in this way the forces during the collision are internal and the moment is conserved
initial instant. Just before dropping the particles
p₀ = 0
final moment
p_f = m_a v_a + m_b v_b
p₀ = p_f
0 = m_a v_a + m_b v_b
tells us that
m_a = 8 m_b
0 = 8 m_b v_a + m_b v_b
v_b = - 8 v_a (1)
indicate that the transfer is complete, therefore the kinematic energy is conserved
starting point
Em₀ = K₀ = 73 J
final point. After separating the body
Em_f = K_f = ½ m_a v_a² + ½ m_b v_b²
K₀ = K_f
73 = ½ m_a (v_a² + v_b² / 8)
we substitute equation 1
73 = ½ m_a (v_a² + 8² v_a² / 8)
73 = ½ m_a (9 v_a²)
73/9 = ½ m_a (v_a²) = K_a
K_a = 8,111 J
