you have 22 degrees as the top angle and the Ac in a right angled triangle. 90-22 = 58. Is that right, I'm not sure. tan(58) = g / 0.7

so I tried ac = 0.2572 / 0.094 = 0.7 ms-2 tan(90-22) = g / 0.7 g = 1.12 1.12 = (6.67 x 10-11)M / (1.5 x 105)2 and I got M = 3.78 x 1020 which is wrong. I'm not sure how to go with this one

Homework Statement It is possible to determine the mass of a planet or large moon by using a ‘pendulum bob’ horizontal circular motion experiment. A cosmonaut on the moon finds that a 25 cm long ‘pendulum bob’ moving in uniform horizontal circular motion makes an angle of 22° to the vertical...
