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....

If I substract 2pi from 7.11 I get 0.83... will that be the angle???

But 7.11 is just more thatn one complete revolution, then that's not the right anwer?

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...

T:3s F:0.33Hz T= 1/F F= 1/T

24.5 m/s*3s= 73.5m

The answer above is very stupid

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

my mistake. the weight is 150 kg not 1500, and .3 m = 30 cm

can you explain how you derive that equation?

we haven't learned about potential energy yet? is there another way to solve this?

I would assume in the same direction as the train

What’s the answer homie
