A mass is attached to the end of a spring and set into oscillation on a horizontal frictionless surface by releasing it from a stretched position of x = +0.150 m. The mass of the block is m = 0.707 kg, the force constant of the spring is k = 73.3 N/m. Determine the following. () force component that the spring exerts on the block just before the block is released (Indicate the direction with the sign of your answer.) N b) angular frequency w of the resulting oscillatory motion rad/s c) maximum speed of the oscillating mass m/s (d) magnitude of the maximum acceleration of the oscillating mass m/s2A child bounces in a harness suspended from a door frame by three elastic bands. (a) If each elastic band stretches 0.250 m while supporting a 7.15-kg child, what is the force constant for each elastic band? N/m (b) What is the time for one complete bounce of this child? S (c) What is the child's maximum velocity if the amplitude of her bounce is 0.250 m? my/S
