What is a passing mechanic cues to remember when you are the receiver of a pass in hockey?
VARVARA [1.3K]

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

One end of a spring with a force constant of k = 10.0 N/m is attached to the end of a long horizontal frictionless track and the
koban [17]

Answer:

-2.478

0.379

11.14

24.78

Explanation:

Angular frequency of spring in harmonic motion is given by?

ω = √(k/m)

ω = √(10/2.2)

ω = √4.54

ω = 2.13 s^-1

If at t=0 the mass is in negative amplitude (x = -A = -2.48 m) then we describe the position with negative cosine

x(t) = -A * cos(ωt)

x(t) = -2.48 * cos(2.13 * 1)

x(t) = -2.48 * 0.9993

x(t) = -2.478

Velocity and acceleration are 1st and 2nd derivative of position

b)

v(t) = Aω * sin(ωt)

v(t) = 2.48 * 2.13 * sin(2.13 * 1)

v(t) = 5.282 * sin2.13

v(t) = 5.282 * 0.03717

v(t) = 0.379 m/s

c)

a(t) = Aω^2 * cos(ωt)

a(t) = 2.48 * 2.12² * cos(2.13 * 1)

a(t) = 2.48 * 4.494 * cos2.13

a(t) = 11.15 * 0.9993

a(t) = 11.14 m/s²

d)

F = -k * x(t)

F = -10 * -2.478

F = 24.78 N
