So I got the problem correct up to the point that I derived the initial velocity in the x direction, 0.24 m/s. After this point, I do not understand the methodology behind this problem.
The teacher told me to use the equation x=v1xt, plug in my given values, and solve for t to get 3 seconds...
I first plugged my given values into m1v1+m2v2=(m1+m2)vf.
(0.002)(600)+(5)(0)=((0.0020)+(5))vf
vf=0.24 m/s
Next, I plugged my given values into F=ma.
((0.002)+(5))(9.8)
F=49.02 N
Next, I plugged my given values into Fdeltat=mdeltav.
deltat=mdeltav/F
((0.002)+(5))(0.24)/(49.02)...
5) So I used your suggestion and plugged my values into the equation.
g=(6.67x10^-11)(1.79x10^27)/(7.04x10^7)=1.70x10^9 N
6) I redid 6a and got a different answer.
v=√(g.g7x10^-11)(5.97x10^24)/(6400100)=7888 m/s^2
Using that answer I redid 6b.
7888=2pi(6.4x10^6)/T=5096 s= 84.94 min
I am...
In hindsight, I don't understand my attempted strategy for Problem 5. Would you care to explain the process of solving it? Thanks!
This was a test, and the teacher did go over the answers, but I do not understand how to complete them.
