Two Physics Problems

1. Figure one in the attached diagram indicates the path through space of the water balloon. On the diagram, place arrows indicating the:

(a) velocity vector
(b) the acceleration vector for te balloon.

Label which is which. Do this for the three points indicated on FIGURE 1.

7. The plot (in the figure attached) shows the relationship of force versus amount of "stretch' for a particular spring.

(A) What is the force constant (in N/m) for the spring?
(B) If I hang a 0.50kg mass from the spring, and start it oscillating, what will be the angular velocity of the oscillation, in rad/s? What would be the period for the oscillations?


Solution Summary

This solution involves labeling vectors and plots, and involves concepts of velocity, force, and acceleration.
