1) A 250 g air track glider attached to a spring oscillates with maximum speed 0.97 m/s. The spring has a spring constant of 450 N/m. a. What is the amplitude of oscillation? b. At what distance from the equilibrium position will the glider have a speed of 0.43 m/s? 2) Like most animals who walk to get around, elephant bob up and down as they walk. The figure shows the vertical component of the velocity of a walking Asian elephant. a. If you were riding on the elephant's back, from the lowest point in your motion to the highest, how far would you travel? b. What is the maximum acceleration (in the vertical direction) of the elephant? c. Write the equation of motion for the elephant. In other words what is y(t)? Vertical velocity of walking Asian elephant vy (m/s) 0.1 +t(s) 0.2 0.4 -0.1 1) A 250 g air track glider attached to a spring oscillates with maximum speed 0.97 m/s.
