Answer: Both A and B

Explanation:

The objects are in contact so it would depend on the amount of force that is pressing them as to the amount of friction and it would depend on the smoothness as too the amount of friction that is added

Provide at least three reasons why friction is needed.

Anarel [89]

Without friction, we would not be able to stop walking since we would just keep slipping like on ice.

Without friction, objects would just slip and fall with a simple blow of air

And finally without friction we wouldn't be able to use machinery like cars and etc since they would just fly off

A baseball is thrown 50.0m in 3.0s, what is the average speed of the baseball? Calculated answer is 16.666667! What is the corre

castortr0y [4]

Answer:

20m/s

Explanation:

Given parameters:

Distance of throw = 50m

Time = 3s

Unknown:

Average speed = ?

Solution:

Average speed is distance divided by time;

Average speed = $\frac{distance }{time}$

Insert the parameters and solve;

Average speed = $\frac{50}{3}$ = 16.66667m/s = 20m/s

You are given directions to a friend’s house from your school. They read: “Go east one block, turn north and go 4 blocks, turn w

julsineya [31]

Answer:(0,2)

Explanation:

Take origin (0,0) as point A and when you move one block east to point B then coordinates becomes (1,0)

Now you move 4 blocks north to point C then the coordinates of point C becomes (4,1)

Similarly, You move 1 block west to point D such that its co-ordinates becomes (0,4)

Finally you move from D to E, 2 blocks south such that point E becomes (0,2)

So, E is the friend's house and its coordinates are (0,2)

It can be diagramatically be represented by figure given below
