1.) If the curling stone was initially sliding at 2.97 m/s and stopped precisely 10.8 meters from its launch point, then the coefficient of friction (the ratio between the magnitude of the frictional force and the magnitude of the normal force) was? 3.) Two curling contestants...
Forces of 86 N east, 23 N north, 46 N south, 55 N west are simultaneously applied to a box of mass 13.8 kg. Find the magnitude of the box's acceleration?
John and Joan walk in opposite directions around a circular path, starting from the same point. The path has a radius of 50.0 meters. John walks at 1.00 m/s, Joan at 1.25 m/s. How long will it take for them to meet? Can someone please explain this to me?! I keep getting it wro...
Physics PLEASE HELP
Nitrogen gas molecules, which have mass 4.65×10−26 kg, are striking a vertical container wall at a horizontal velocity of positive 440 m/s. 5.00×1021 molecules strike the wall each second. Assume the collisions are perfectly elastic, so each particle rebounds...
A net force of 30 N is applied to a 10 kg object, which starts at rest. What is the magnitude of its momentum after 3.0 seconds? Can someone please explain this as you go through the steps? I already know the equation is p=mv and I know that mass is 10kg and I just need v...
Find the volume or the solid generated by revolving around the region bounded by the graphs of the equations about line x=6. xy=6, y=2, y=6, and x=6
math (please double check my answers)
4. Prove: 2^n + 2^n = 2^n+1
6. Determine the domain and range for each function given. Explain where any restrictions come from. a. f(x)= sqrt x + 5 4 b. f(x) = 1/2x^2 32 c. f(x) = 4/x^2 + 1
Solve the equation. If necessary, round to the nearest thousandth. 5(2x-1)=10
Suppose the spring in this spring-powered rifle has a spring constant of k = 1,000 N/m. How much work can it do in accelerating the projectile, if it is compressed by x = 0.10 m?
