    Calculating Force Constant of a Spring

    Phew, good to know I'm getting somewhere. Thanks PhanthomJay! And thank you for your input Kreamer! You just forgot to include elastic potential energy :)

    Calculating Force Constant of a Spring

    A spring is suspended from a celing and a 0.256-kg mass is attatched to it and pulled down to stretch the spring by 0.182 m. The mass is released and travels through the equilibrium position with a speed of 0.746 m/s. Calculate the force constant on the spring. I'm not really sure how to...

    How Does the Work-Energy Theorem Determine the Initial Speed of a Sledgehammer?

    It would be negative. But how is the net force on the pin acting upwards?

    How Does the Work-Energy Theorem Determine the Initial Speed of a Sledgehammer?

    Homework Statement 490 J of work is done on a pin when a 5 kg sledgehammer strikes it (bringing the sledgehammer to rest). What is the initial speed of the sledge hammer. Homework Equations (Fnet)(d)= (0.5)(m)(velocity final^2 - velocity initial^2) The Attempt at a Solution...

    Force exerted by one object on another?

    What force does the 4.0 kg object exert on the 10 kg object when the two are moving together? Ofcourse, I know I did not put the previous, required information in order to solve this question. I would like to know in general how to find the magnitude of force one object exerts on another in...

    Calculating Average Acceleration for a Slow, Level Turn

    Homework Statement An airplane flying at a constant speed of 1000 km/h executes a slow, level turn that changes its direction from west to east. If the turn takes 80 s, calculate the plane's average acceleration. Homework Equations average acceleration = average velocity/time The...

    Simple 2-D Uniform Motion Problem

    Unfortunately, this problem isn't that simple. The answer given is: a) 50 m/s [W37*N] b) 260 m [W21*N] I assume it is required for me to draw a vector diagram, but the fact that this problem involves acceleration is what is confusing me.

    Simple 2-D Uniform Motion Problem

    A ball rolling with an initial velocity of 40 m/s [W] undergoes an acceleration of 5.0 m/s^2 [N] for a period of 6.0 seconds. a) What is the final velocity of the ball? b) What is the displacement of the ball in the 6.0 seconds? Can someone explain how I would draw this vector...

    Finding Force of Contact: 2kg and 3kg Blocks with 10N Horizontal Force

    Hello mezarashi :) Alright, I drew each of those FBDs. I found the acceleration of the system, which was 2.0 m/s^2. I used the acceleration, and found the Fapp on mass A, which was 4.0 N. And Fapp for mass B is 6.0 N. The external forces are Force normal, and force applied. I'm still a...

    Finding Force of Contact: 2kg and 3kg Blocks with 10N Horizontal Force

    A 2-kg block A and a 3-kg block B are in contact on a frictionless table. A horizontal force of 10N is applied to A. Find the force with which B resists the pressure of A. The answer is -6N. I realize this is a very simple question, I would just like to understand how to get the solution...
