A 5.00 kg glider on an air track is attached to the end of an ideal spring with force constant 454 ; it undergoes simple harmonic motion with an amplitude of 4.00×10 −2 ? A. Compute the maximum speed of the glider? Vmax = Squareroot of K/M x (A) = 454/5 square rooted (4.0x10 -2m) = 0.381 m/s B. Compute the acceleration of the glider when it is at its maxumim speed? a. X=0 asnwer a= -(k/m)x= 0 m/s^2 C. Amax = (-454n/m/5kg) (-4.0x10^-2)= 3.63m/s^2 D. Et = 1/2kA^2 = ½(454n/m)(4/0x10-2m)^2 = 0.363 J
