Like this...? F (M_e)(M_s) / (R_es)^2 = F (M_s)(M_m) / (R_ms)^2 ? :confused: es - Earth/ship ms - moon shop

Homework Statement Transplanertay tours promises tour participants a certificate to commemorate their passage from the stronger influence of Earth's graviational pull to the stronger pull of the Moon at the point where the two forces on your spaceship are equal. Where on the trip should you...

Does that make sense, or do you want me to be more specific? :smile: Could you be more specific? The question says that the segments are free to pivot. Why is this relevant to finding tension? Hahaha, i think I'm just overthinking it and that's why I'm not fully understanding it.:frown...

Homework Statement An object of mass m attached to a spring of force constant oscillates with simple harmonic motion. The maximum displacement from equilibrium is A and the total mechanical energy of the system is E. What is the object's velocity when its potential energy is 2/3 E ...

I don't know if I fully understand the question. I know I'm looking for the tension in the top joint. But why does torque apply here? Why use torque equations if it isn't moving. Physics frustrates me...lol

Homework Statement A bridge, constructed of 11 beams of equal length and negligible mass, supports an object of mass as shown. Real bridges of this sort have steel rockers at the ends, these assure that the support forces on the bridge are vertical even when it expands or contracts...
