i seem to be getting the wrong answer...
for circumfrence i am getting 471.23m
therefor the distance = 942.4m
and then to find time i used time=distance/speed and got 5.2s
my textbook has different answer.
Am i wrong or is there an error in the book?
but how would i find the distance in an arc? should i use the equation for circumfrence of a circle? or should i assume it as if it is a straight line?
Also after finding the distance of the first arc i can multiply it by two right ?
Homework Statement
A pilot is flying his personal jet at 180m/s, approaching the airport. Near the airport the pilot sees the runway 300m horizontally to his left, but he is moving parralel to it. He banks left quickly, turning in level, circular arc, until the plane has moved 150 m, then...
ok so pulley A will have 2 tensions up and one tension down
how would i do pulley C?
would it also have 2 tensions pulling up and the mass pulling down?
ok so here's what i got
for pulley A i have 2 tensions pulling up and one pulling down
for B i got on tension pulling up and two pulling down
i don't know if that's right and also how would i do C
