Answer:

A. when the mass has a speed of zero

Explanation:

In mass-spring system, the velocity and the acceleration are in anti-phase, which means that when one of the two quantities is maximum, the other one is zero, and vice-versa.

In fact:

- When the displacement of the spring is zero (x=0), the velocity is maximum, due to conservation of energy. In fact, as the displacement is zero, the elastic potential energy of the system (given by \frac{1}{2}kx^2) is zero, therefore the kinetic energy (given by \frac{1}{2}mv^2) must be maximum, and so the velocity (v) is also maximum. On the cotnrary, acceleration (a) is directly proportional to the restoring force of the spring, given by

F=-kx

so we see that when x=0, then the force is zero: F=0, and so the acceleration is zero as well.

- When the displacement of the spring is maximum, the velocity is zero, due to conservation of energy. In fact, as the displacement is maximum, the elastic potential energy of the system (given by \frac{1}{2}kx^2) is maximum, therefore the kinetic energy (given by \frac{1}{2}mv^2) must be zero, and so the velocity (v) is also zero. On the cotnrary, since acceleration (a) is directly proportional to the restoring force of the spring, given by

F=-kx

so we see that when x=maximum, then the force is maximum, and so the acceleration is maximum as well.

Based on this, the correct answer is

A. when the mass has a speed of zero

With what initial velocity must an object be thrown upward from a height of 2 meters to reach a maximum hieght of 200 meters
larisa86 [58]
The equations of motion to use for a constant acceleration a = g = -9.81:
v = gt + v_0
y = \frac{1}{2} g t^{2} + v_0t + y_0

at the highest point the velocity must be zero:
0 = gt + v_0 \\ v_0 = -gt
combine both equations:
y =  \frac{1}{2}  \frac{v_0^{2} }{g}  -   \frac{v_0^{2} }{g}  + y_0=  -\frac{1}{2}  \frac{v_0^{2} }{g} + y_0
Solve for v₀:
v_0 =   \sqrt{2g(y_0 - y)}
