Which of the following is not a common denominator of 2/5 and 3/10
Whats the freaking answer
What’s the answer homie
I would assume in the same direction as the train
we haven't learned about potential energy yet? is there another way to solve this?
can you explain how you derive that equation?
my mistake. the weight is 150 kg not 1500, and .3 m = 30 cm
I found the answer, it is 1142.86 meters. I assume that the river was flowing East. so, the angle = arctan( .8 / 1.4 ) = 29.74 degrees. then tan (29.74) = offset / 2000 m = 1142.86 m
The answer above is very stupid
24.5 m/s*3s= 73.5m
T:3s F:0.33Hz T= 1/F F= 1/T
Oh wait, I was using the angular speed of Mars, using the angular speed of Earth I get 13.4 radians and that will be more than two revolutions so the additional angle is 0.798 rad? Is that right?? Please someone answer...
But 7.11 is just more thatn one complete revolution, then that's not the right anwer?
If I substract 2pi from 7.11 I get 0.83... will that be the angle???
Ok I got the 2 first ones right... 2.94 and my new value for b is 777.... I still cant get the last one, I thought that by multiplying Mars' angular speed and the time I got for part A that was going to be the answer.. I got 7.11 rad but that's wrong....
