1. You are swinging a tin can around your head in a perfectly horizontal circle of radius 4 m. (This is really not possible but we're saying it almost happens.) If the speed of the can is 4 m/s what is its acceleration?
2. You thoughtfully set a 1 kg box on top of a loaf of bread and the loaf compresses by 15 cm. Thinking of the bread as a spring, what is its spring constant?© BrainMass Inc. brainmass.com October 25, 2018, 6:50 am ad1c9bdddf
This solution helps with questions involving speed and spring constants.
Maximum Speed of Mass, Potential Energy & Spring Constant
The position of a 0.500 kg spring as a function of time is given as x(t) = (1.25 m)cos(6.00 t).
What is the maximum speed of the mass? (7.5 m/s)
What is the spring constant for this spring? (18 N/m)
What is the maximum potential energy of this spring? (14 J)
The answers given are in parenthesis. I'm just stuck. Thank you!View Full Posting Details
