math
A boat traveling downstream a distance of 39 miles then came right back.If the speed of the current was 12 mph and the total trip took 4 hours 20 minutes,find the average speed of the boat relative to the water.

physics
A crate is sliding down a ramp that is inclined at an angle of 55.4° above the horizontal. The coefficient of kinetic friction between the crate and the ramp surface is 0.501. Find the acceleration of the moving crate.

math
Im afraid i dont even know where to get started. im new to my course and i havent studyied anything like this before.

math
pretty stuck on this one, any help apreciated: the angular displacement (feta) of a shaft is given by feta= 1/2 (cos-5t. Find the velcoity of the shaft w at t= 2s my apologies for the improper layout.

Physics-Someone please recheck
Bob Pursley rechecked my question and it was correct if you scan down but he didn't direct me where to find direction of magnetic force on plane and do the pilots have to make corrections to make up for the difference? I'd appreciate any help with that, if possible Th...

Physics-bobpursley please recheck
Thank you for pointing that out-I totally forgot to put it back in Could you direct me for the direction and if corrections have to be made by pilots-I'm not sure how to figure that out

Physics-Check what I have, please
I think the formula is F = q(v*B) so therefore I would say F= 50 C(1000*50T), correct or not?? I'm still not sure about the direction or if they have to make correctins to their controls

Physics-I forgot the magnetic field calc
I forgot that the earth's magnetic field is 50 micro Tesla

Physics
If a aircraft flie at 1000m/s east it accumulates a 50C of charge as it passes a cloud. How would I calculate magnitude of magnetic force, direction of magnetic force on plane and do the pilots have to make corrections to make up for the difference? Thanks in advance for any help

Physics-Please check answer
That's what I thought-wasn't sure though-thanks

Physics-Please check answer
Damon helped me with this calc but I think the answer should be -20, not -22, could someone please check the calculation If a ball is thrown into the wall at 14 m/s and comes off at 6 m/s, what is change of velocity of the ball? I think it would be 14-6 = (-8 m/s) Is that corr...

Physics-could someone check
Damon helped me to solve this problem but I think it adds up to -20 not -22, correct?

Physics-shouldn't it be -20 instead of -22
Shouldn't it be -20,not -22

Physics
If a ball is thrown into the wall at 14 m/s and comes off at 6 m/s, what is change of velocity of the ball? I think it would be 14-6 = (-8 m/s) Is that correct?

Algebra-please recheck Reiny
I'm not sure I'm understanding the x= 400 tan 30 *230.94 or would it be that it equals 230.94
