A book falls off a 1-meter tall table. how long will it take for the book to hit the floor ?

0.45 s

Explanation:

Step 1: Given and required data

Step 2: Calculate the time that it will take for the book to hit the floor (t)

The book undergoes a Uniformly Accelerated Motion. We can calculate the time required to reach the floor using the following suvat equation.

s = u × t + 1/2 × a × t²

s = 0 m/s × t + 1/2 × a × t²

s = 1/2 × a × t²

t = √(2s/a)

t = √(2 × 1 m/9.8 m/s²)

t = 0.45 s

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.

explanation:

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
