A pendulum is in a spacecraft to measure
acceleration during lift off. Before the launch, its period
is 6.5 X 10-3 s. At a point during lift off, its period is 3.1
X 10-3 s. What is the acceleration at this point?

For small angles (✓ < 30 degrees), the period of a simple pendulum4can be approximated by: 3A radian is an angle measure based upon the circumference of a circle C =2⇡r where r is the radius of the circle. A complete circle (360 ) is said to have 2⇡ radians. Therefore, a 1/4 circle (90 )is⇡/2 radians.
