Hi Elena, The equation I used for to solve for Va is sqrt((5/4)*(G*m_1/r_1). It came out wrong. Is this the correct equation. Thanks.
Hi Geoff, Thanks for the tip. I would have entered it as entered my answer as -3.666. I entered as positive 3.666 and it was correct. Good call.
For question 5 ballistic missile m1= 5*10^24kg; r1=6000km; m2
ellie, Thanks. I thought this is the most difficult question. I had trouble with these type of problems throughout the course. I do not have any suggestions. at this point.
Hi, Enjoy. I responded but I do not know what happened. f=force - (m*a) , 22-(2)*(12.83 3)= -3.666. x-componet in negative x direction. I am up to my last chance as on most problems. I need help on question no.1. Thanks.
Hi enjoy. I tried F=force - m*a = 22-(2*12.8333) = -3.6666 in the negative x direction. I am down to my last chance. Like with all the problems. Thanks, I am trying to keep my head above water. I still have a long way to go. I also had trouble with
Hi enjoy, I got the acceleration correct, but the x component of the friction force incorrect in part b. Question no. 2 on torque is confusing from the top view CW or CCW. Thanks.
a=[F*(R+r)]/[(l/R)+m*R)] a=[22*(0.25+0.1875]/(0.0625/0.25)+2*(0.25) a=12.8333 This was correct. one of the few I got right. Part b is wrong. Need help on question 2 (torque) I am confused about the top view. I thought I understood it but I guess I don't.
