64. (a) R4 5 2.50 x 102
I1 = 0.250 A
I2 = 0.150 A
I4 = 0.100 A
(b) V2 = 16.7 V
V3 = 8.30 V
This is the answer from the back of the textbook... Also my teacher said to use the basics aka... I am not suppose to ground!
a) is it 99.05 m/s (also do i use the same height)
b) for this I have to do every height there is?
c) how is D 5? in the diagram you only have 5.5 and/or 0.5!
Homework Statement
A 1000kg roller coaster, with its passengers, starts from rest at point A( h= 9.5 m) on a friction track whose profile is shown in the diagram above at right.
a) what is its maximum speed?
b) with what speed does the roller coaster arrive at point e?
c) What constant...
Woah what. :S Ok you said to use the 2ax = (vf)^2 - (vi)^2. and I got 6666.5 m/s^2. is it wrong? does that mean I have to go back to my original idea? Now I am beyond confused.
