What is the y-component of force on astronaut's jump on the Moon?

AI Thread Summary
To calculate the y-component of the force on an astronaut jumping on the Moon, first determine the total weight of the astronaut and space suit, which is 370 lbs (190 lbs + 180 lbs). Convert this weight to mass in kilograms using the conversion factor (1 lb = 0.453592 kg), resulting in approximately 168.5 kg. On the Moon, the acceleration due to gravity is about 1.625 m/s², so the force can be calculated using F = mass × acceleration, yielding approximately 274.5 Newtons acting downward. The y-component of the force refers to the net force in the vertical direction, which is influenced solely by the Moon's gravity. Therefore, the force acts downward during the astronaut's jump.

Homework Statement



Suppose the astronaut has a weight on Earth of 190 lbs and is wearing a space suit that weighs an additional 180 lbs on Earth. What is the y-component of the force in Newtons on the astronaut and his space suit during a jump on the Moon? Show your calculation. Does the force act upward or downward?

Homework Equations


I'm not sure how to address this problem- I know that the net force= mass X acceleration. Is the y component of the force that they're asking for the same as the net force?

the only force is the Moon's gravity, and that's down

the y component of force is the component of the net force in the positive y-direction :smile:

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
