Answer:

is always negative

Explanation:

Air resistance is a non-conservative force it opposes the motion of an object.It is a force that is always directed opposite to the displacement.

Answer:

C. Is negative.

Explanation:

Work is the dot product of force and displacement. This means that a force acting in the direction of motion will do positive work. The same applies for a force acting in opposite direction will do net negative work.

Gemiola [76]

you tend to push off with the foot still on the boat.

Newtons 3rd law of motion hold that every action has an equal and opposite reaction.

So, the amount of force you use on your back foot to push yourself onto the dock, has an equal end opposite amount of force going the other way from your sole of your foot, which pushes the boat the other way.

The same principle applies when you fire a cannon - in the pirate films, you see the body of the cannon forced back as it is fired.

Take it one step further, Henry VIII flagship, “Mary Rose fired all its cannons together one day in a broad side, the opposite force rolled the ship over and sank it.

Answer:

Centripetal acceleration will be equal to 10.66m/sec^2

Explanation:

We have given time taken to cover 180° is 0.5 sec

So time taken by 360° is equal to = 2×0.5 = 1 sec

Radius of the circle r = 0.520 m

So distance d=2\pi r=2\times3.14\times 0.520=3.2656m

So velocity v=\frac{distance}{time}=\frac{.2656}{1}=3.2656m/sec

We have to find the centripetal acceleration

Centripetal acceleration will be equal to a_c=\frac{v^2}{r}=\frac{3.2656^2}{1}=10.66m/sec^2

So centripetal acceleration will be equal to 10.66m/sec^2
