Homework Statement A mass is attached to a spring on a frictionless horizontal surface. The mass is pulled to stretch the spring by 0.1 m, & then gently released. A short time later, as the mass passes through the equilibrium position, its speed is 1 m/s. Part a) What is the speed of...

Hey quick question, how do I solve this using the physics method and not the pre-calculus method like I did above using SOHCAHTOA?

Homework Statement A 32-u oxygen molecule (O2) moving in the +x-direction at 580 m/s collides with an oxygen atom (mass 16 u) moving at 870 m/s at 27° to the x-axis. The particles stick together to form an ozone molecule. Find the ozone’s velocity. Homework Equations The Attempt...

I'm a bit confused. The value I got, 14.523 units, is that the answer for part b, which is to find the magnitude? So if I understand what you're saying, part a is to either draw the vector on the diagram or write out the components. Example answer is Vector C = 6.27i + 13.1j units.

Homework Statement Vectors A and B are shown in the figure. Vector C is given by C=B-A. The magnitude of vector A is 15.0 units, and the magnitude of Vector B is 5.00 units. Part a) Find the vector C? Part b) What is the magnitude of vector C? Homework Equations SOHCAHTOA...

Oh thank you. I got the correct answer with formula, v = ( r ) ( w ). My teacher put the correct answer on the problem for some reason. Thank you.

Homework Statement A bug crawls outward from the center of a CD spinning at 200 revolutions per minute. The coefficient of static friction between the bug’s sticky feet and the disc surface is 1.2. How far does the bug get from the center before slipping? What is the speed of the bug just...

Oh that makes sense now ehild. Thanks a lot guys, the help is much appreciated.

This is what I've gotten so far. Since "require that the cable tension never exceed two-thirds of the breaking tension" : F = ma F = (2/3)*(19500) F = 13000 Max Acceleration = 2.24 m/s^2 Acceleration due to gravity = 9.81 m/s^2 Acceleration = 2.24 + 9.81 = 12.05 m/s^2 So, F =...

Homework Statement 1) An elevator cable can withstand a maximum tension of 19,500N before breaking. The elevator has a mass of 490 kg and a maximum acceleration of 2.24 m/s2. Engineering safety standards require that the cable tension never exceed two-thirds of the breaking tension. How may...
