Problem 4.11
A mass of 100 gm hung on a spring was set in motion. A movie camera with a
framing rate of 20 frames per second was used to photograph the mass.
The values for the displacement of the mass obtained by reading each frame
of the film are listed in the table below (the one in the book
is bit off). How were the velocities determined? How were the accelerations
determined?
Does a constant force act on the mass? What produces the force?
| t(s) |
d(cm) |
v(cm/s) |
a(cm/s2 |
