We think it is one whole. But how do you show your work, and is that the answer.

A man is traveling 9.8 m/s. When he reached his destination he was traveling 31.6 m/s. He knows his acceleratin was 5 m/s (2nd power). How long did it take him to get there. PLEASE SHOW WORK, it will help me do the rest of these questions. Appreciate any help I can get

I know this sounds strange but I think I have a magnetic field or just a stronger one than usual. heres my reasoning. 1. any electronics that stay close to me stop working after short times use. t.v.s, remotes, power strips. anything that spends time with in so many feat of me stops working after a while. 2. if you put a walky talky next to me you get more than static. I know because at the place I worked my boss used to make people think he had a metal detector but it was just a walky talky. nobody else got that kin off reaction out of it. last but not least. 3. if I stand near radios they get better reception.

so what do you think. do I have a magnetic field.

Are you good at biology? if so please give this one a try!?
1) why is it important that solutions added to the blood stream must be isotonic with the blood plasma?

2) why does the salt runoff from winter roads kill nearby plants? please explain this clearly, i think it has to do with osmosis

THANKS :)

A force of 105 N is applied horizontally to a 20.0 kg box to move it across a horizontal floor. If the box has an acceleration of 3.00m/s^2, find the coefficient of friction.

I know F=ma is used somehow, but where do I use it? Help please!

A ball of mass 0:4 kg, initially at rest, is
kicked directly toward a fence from a point
20 m away, as shown below.
The velocity of the ball as it leaves the
kicker's foot is 17 m=s at angle of 51 ± above
the horizontal. The top of the fence is 7 m
high. The kicker's foot is in contact with the
ball for 0:04 s. The ball hits nothing while in
°ight and air resistance is negligible.
The acceleration due to gravity is 9:8 m=s2.


What is the vertical component of the velocity
when the ball reaches the plane of the fence?
Answer in units of m=s.
