Ok, I see. If I remember correctly, then 2 waves that constructively interfere have Amplitudes that add up to the Resultant wave amplitudes. But I'm having trouble relating this to the wavelengths. Pardon my lack of knowledge with interfering waves, my lecturer skipped over it and only talked...

The Attempt at a Solution
Basically, I tried to...
For those who are solving any problem like such in the future.
The original equation I used was correct but you have to factor in that you also have the force of gravity that acted on the spring as well. So the Total net force is:
Fnet=((mass given)*(acceleration given)) + ((mass...
Cyosis is right, you want to solve for the x component of the force which is the cosine of the angles, also you have two teenagers pulling in that direct thus two such forces. Add those resulting forces to the opposite of the force created by the snow and that is your net force.
and as...
If I follow what you are saying. You want me to find the upward resulting force from the spring compression using the given mass of 28.86kg and multiply that my the acceleration given 4.802 m/s^2 and set that equal to the spring constant times the distance x.
F=(mass given)(acceleration given)...
1) A 28.86 kg child bounces on a pogo stick. The pogo stick has a spring constant 18016 N/m. When the child makes a nice big bounce, she finds that at the bottom of the bounce she is accelerating upwards at 4.802 m/s2. How much is the spring compressed?
Given:
Mass of Child: 28.86kg

Homework Statement
A 1.02 kg ball and a 2.06 kg ball are connected by a 0.95 m long rigid, massless rod. The rod is rotating clockwise about its center of mass at 38 rpm. What torque will bring the balls to a halt in 8.53 s? (Give an absolute value of torque.)
