We examine the projectile motion of a disk on an inclined plane that makes an angle o (sin o = 0.1) with the horizontal. The y-axis is oriented along the inclined plane and the x-axis along the plane perpendicular to the y-axis, as shown in the figure. At t = 0, the disk is thrown from the origin of the coordinate system with an initial velocity V that makes the angle e = 53° with the x-axis (sin 53° = 0,8, cos 53° = 0,6). The frequency of the spark timer is 10 Hz Using the measurement results in the following table: Fig

We examine the projectile motion of a disk on an inclined plane that
makes an angle o (sin o = 0.1) with the horizontal. The y-axis is oriented
along the inclined plane and the x-axis along the plane perpendicular to
the y-axis, as shown in the figure. At t = 0, the disk is thrown from the
origin of the coordinate system with an initial velocity V that makes the
angle 0 = 53° with the x-axis (sin 53° = 0,8, cos 53° = 0,6).
The frequency of the spark timer is 10 Hz. Using the measurement results
in the following table:
