How can I practice good wrist action in my golf swing?

I was playing today and my drives and irons where slicing left. I realized I was not using my wrists enough so i flipped them through more and I started to pull the ball. I am wondering any good wrist action tips or drill to hit the ball straight with my driver and irons.

A heavy swing door has a mass?

A heavy swing door has a mass of m = 4,000 kg, a width w = 1.9 m and a height H = of 3.1 m. The door swings about a vertical axis passing through its center.
http://www.webassign.net/ncsuplsemech2/7-post-003a.gif

(a) What is the moment of inertia of this door about the vertical axis passing through its center? Use
I = (1/12)Mw^2

(b) You stand on one side and push at the outer edge of the door and perpendicular to the face of the door with a force of F = 6 N. Your friend pushes on the other outer edge of the door from the opposite side with the same force. What is the magnitude of the net torque applied to the door?

(c) What is the magnitude of the angular acceleration of the door?

(d) Consider a heavy door with the same mass and dimensions that swings about a vertical axis passing through one long edge.

What is the moment of inertia of this door about the vertical axis passing through one long edge? Use I = (1/3)Mw^2

(e) What is the magnitude of the net force you and your friend must apply to the free end of the door and perpendicular to the plane of the door in order to produce the same torque as that produced by both of you in part (b) above?

(f) What is the magnitude of the angular acceleration of the door?

How do i fix my golf swing (irons)?

Sometimes out of nowhere I will shank my shot straight to the right but I can’t tell what the difference is in that and my normal swing. Today I went to the driving range and I was either slicing or skimming it along the ground in front of me. I know its mostly a mental thing, but i can’t figure out how to fix it!

Pendulum Problem?

I just don’t get these pendulum problems. Could someone tell me how to go about them…

A pendulum is formed by attaching a mass, m = 0.25 kg to the end of a string of length L = 1 m. The other end of the string is attached to a nail so the pendulum can swing in a complete circle in the vertical plane. There is no friction between the nail and the string.

The mass is released from rest with the string at a 60° angle with respect to the vertical as shown. What is the speed, v, of the mass when the angle between the string and the vertical is 30°?

a)v = 1.52 m/s
b)v = 1.69 m/s
c)v = 1.81 m/s
d)v = 2.12 m/s
e)v = 2.68 m/s

The pendulum is now set in motion in such a way that it swings in a complete vertical circle with the tension of the string being equal to the weight of the mass at the top of the circle. What is square of the speed, vb2, of the mass at the bottom of the swing (i.e., the lowest point in the swing)?

a)vb2 = 3gL/2
b)vb2 = 2gL
c)vb2 = 5gL/2
d)vb2 = 4gL
e)vb2 = 6gL

A 0.400-kg object attached to the end of a string of length 0.500 m is swung in a circular path and in a?

(question continued) vertical plane. If a constant angular speed of 8.00 rad/s is maintained, what is the tension in the string when the object is at the top of the circular path?
a) 18.88 N
b) 10.5 N
c) 12.8 N
d) 19.6 N
e) none of these

How to improve your golf swing and how to use a range finder?

Is it better to lean back on your back foot or not?

And I also have a golf range finder and don’t know how to use it, it’s not electronic just a scope with a bar that says green and above that has marks with yard numbers, how am I supposed to use it?
