Question

11. (a) Given the mass of Jupiter is 1.90x10^27 kg, and that Jupiter has an equatorial, radius of 71,492 km what is the acceleration due to gravity on Jupiter? (b) How much would a 135 lb person weigh on Jupiter (1 kg = 2.2 lb)? 13.Apply conservation principles to find the initial speed vi of a 10.5 g bullet shot into a 2.55 kg block attached to a spring with a force constant of 245 N/m, given that the max compression of the spring caused by the bullet is 17.5 cm. 14. If we can approximate a grandfather clock as a simple pendulum then what Length will its pendulum have to be to keep accurate time (note, it should take exactly 1.00 s to swing half a period, show your work ...)?

Explanation / Answer

As

g = G M / R^2

Then

g = 24.8 m/s^2

Thus,

W = m g = 7370 N   [ANSWER]
