8.
Velocity vector will be upwards
and Accelaration vector will be upwards
so the net fore vector will be upwards
Velocity = 0 (just at lowest point)
Accelaration, force = positive(or in the direction of movement)

" A mass hanging from a vertical spring is somewhat more complicated than a mass attached to a horizontal spring because the gravitational force acts along the direction of motion. Therefore, the restoring force of the oscillations is not provided by the spring force alone, but by the net force resulting from both the spring force and the gravitational force. Ultimately, however, the physical quantities of motion...

Referring to the motion of the mass in Figure 7-2, plot its position immediately below it in Figure A. 7-3. B. Repeat this process, but now watch for the velocity of the mass. Plot its relative velocity (maximum speed up, maximum speed down, or zero) on Figure 7-3. Which trig function does this resemble? C. Repeat this process one more time, but now watch for the acceleration of the mass. Plot its relative acceleration (maximum up, maximum down, or zero)...

A mass on a spring moving along the x-axis in simple harmonic motion starts from the equilibrium position, the origin, at -0 and moves to the right (consider the right to be the positive x direction). The amplitude of its motion is 1.75 cm and its period is 0.667 s. You observe the motion for 5 seconds. a. At what time(s) in those 5 seconds do you observe the n 3. x=0 +X Ax acceleration? At what time(s) does in...

Exactly two forces press on a 2.95 kg mass, both on the x-axis (the force is positive if it points in the +x direction and negative otherwise), starting at time t=0. The first has a value of F(t)=3.7sin(wt) and the second has a value of F2(t)=-2.0cos(wt). Both forces are in N and the time is in seconds. The value of w is 1.85 rad/s.(w is omega) At t=0, the velocity is +3.0 m/s in the x-direction. Gravity does not act...
