Question

Constants Part A A 2 10 kg mass is pushed against a horizontal spring of force constant 26 0 N/cm on a air table. The spring is attached to the tabletop, and the mass is not attached to Find the greatest speed the mass reaches d enough to store 15.0 J of the spring in any way. When the spring has been co potential energy in it, the mass is suddenly released from rest. x 3.78 m/s Completed - Part B When does this occur? Essay answers are limited to about 500 words (3800 characters maximum, including spaces) 3800 Character(s) remaining Part C @niit..

Explanation / Answer

m = 2.1 Kg

K = 26 N/m

Energy = 15 J

part A) the greatest speed of the mass reaches is v

15 = 0.50 * 2.1 * v^2

v = 3.8 m/s

the speed of the mass is 3.8 m/s

b) this occurs at the equilibrium position

c) let the maximum compression is x

0.50 * 26 * x^2 = 15

x = 1.07 m

let the maximum acceleration is a

m * a = k * a

2.1 * a = 26 * 1.07

a = 13.25 m/s^2

the acceleration is 13.25 m/s^2
