Q1. A certain metal with atomic mass 2.6 × 10-25kg has an interatomic bond with length 1.7 × 10-10 m and stiffness 47 N/m. What is the speed of sound in a rod made of the metal?
Q2. The coefficients of friction for plastic on wood are μs = 0.50 and μk = 0.40. How much horizontal force would you want to apply to a 4.0-lb plastic calculator to start it moving from rest?
Q3. Two bicycle tires are set rolling with the similar initial speed of 4.00 m/s along a long, straight road, and distance each travels before its speed is reduced by half is measured. One tire is inflated to a pressure of 40 {rm psi} and goes a distance of 17.8 m; other is at 105 {rm psi} and goes a distance of 93.5 m. suppose that the net horizontal force is because of rolling friction only and take the free-fall acceleration to be g = 9.80 m/s^2. What is the coefficient of rolling friction mu_r for tire under low pressure?
