In order to measure the free-fall acceleration on a distant planet with no orbiting satellite, a 1.5-meter-long pendulum made of a massless lead string holding a very small 2-kg gold mass is brought to the planet's surface. The planet has a temperature of 470 °C, and once the pendulum is lifted at an angle of 15° from the vertical, it swings left and right with a period of 2.38 seconds. If the original measurement for the pendulum was taken when the temperature was 25 °C, what is the free- fall acceleration on that planet? Round to the nearest hundredth (0.01). Justify your answer using your rationale and equations used.

When the length L of aclock pendulum is held constant by controlling its temperature,the pendulum’s period T depends on the acceleration of gravity g.The period will therefore vary slightly as the clock is moved fromplace to place on Earth’s surface, depending on the change in g.By keeping track of DELTA T, we can estimate the variation in g fromthe equation T = 2π(L/g)1/2 that relates T, g, and L. A clock with a 100-cm pendulum is moved from a location where g = 980 cm/sec2 to a new location. This increases the period by dT = 0.001 sec. Find dg and estimate the value of g at the new location.
