i know that I can't actually include 24 in my problem as the mass is changing so do I replace 24 with m? and then have my g' cancel at some point?

Homework Statement An astronaut lands on a distant planet with an unknown gravitational field g’. On the bottom of his spaceship, he attaches an ideal frictionless pulley supported overhead with two light buckets hanging downwards, attached by a light rope. He places 24 kg of the same rock...

I was reading over my post and I can't remember, do I include the 300km/h in my orignal component triangle?

°Homework Statement A pilot wishes to fly to city A, 800km north of the present location. The plane is capable of an air velocity of 300km/h. There is a wind blowing 120 km/h [S40°W] a) if she flies directly to city A, what will be her observed ground velocity? b) what should her orignal...

Hmm, I always manage to overcomplicate an easy question. thanks, I calculated my time to be 5.1 secs.

Homework Statement a baseball player hits a home run. The ball's velocity as it leaves the bat is 45m/s at an angle of 36.9° above the horizontal. At the point of impact with the bat, the ball is 1 m above ground level, and as it clears the fence it is back down to 11 m above ground level...

hmm, so if I change my variables in the "knowns for rock" v1: 0 v2: a: -9.8m/s t: t-3 d: and sub into solve for d... d rock = v1t + 0.5at squared = (0)t + 0.5(-9.8)(t-3) squared = -4.9tsquared + 29.4t -44.1 dsound =vt = (330)t 330t = -4.9squared +...
