All angles are measured as anti-clockwise rotations from the +x-axis. An object has an initial velocity of 2.91 m/s at 26.6 degrees. 6.6 seconds later it is moving at 91.15 m/s at an angle of 131.5 degrees. What acceleration caused this change in velocity? (Give your answer in terms of the +x-axis, in degrees)
Acceleration =
,
Angle =
from the positive x axis.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
