block of mass m = 249 grams oscillates to the left and right with negligible friction on the end of an ideal spring with a spring constant of 117 N/m. At the time t = O, the block is a distance 0.145 m to the right of the equilibrium position and it is moving to the right with a speed of 3.1 ms. What is the velocity of the block (in units of meters per second) at the time when t = 0.129 seconds? The sign (positive or negative) of your answer is important. For the purposes of this question, velocity pointing to the right is positive and a velocity to the left is negative.

Question

A block of mass m = 249 grams oscillates to the left and right with negligible friction on the end of an ideal spring with a spring constant of 117 N/m. At the time t = O, the block is a distance 0.145 m to the right of the equilibrium position and it is moving to the right with a speed of 3.1 ms. What is the velocity of the block (in units of meters per second) at the time when t = 0.129 seconds? The sign (positive or negative) of your answer is important. For the purposes of this question, velocity pointing to the right is positive and a velocity to the left is negative.
