A rock is dropped from a bridge what happens to the magnitude of the acceleration

White raven [17]

Answer:

9.81 m/s² constant

Explanation:

Any object which is falling has only the acceleration due to gravity acting on it. The value of acceleration due to gravity is 9.81 m/s² which is constant. This is the case if air resistance is not taken into consideration.

The air resistance is a result of the surface area of the object which is falling. This will slow down the object and the velocity reached is called the terminal velocity.

If an object starting from rest falls 5.7 seconds how far does it fall

White raven [17]

Kinematic question!
Start with your knowns!

$t = 5.7s \\ v0 = 0 \frac{m}{s} \\ a = - 9.8 \frac{m}{ {s}^{2} }$
we want to find x!

the only kineamtic that works with this info is the third!
$x = v0 \times t + \frac{1}{2} \times a \times {t}^{2}$
so we plug in our values and get
$x = 0 + \frac{1}{2} \times ( - 9.8 \frac{m}{ {s}^{2} } ) \times ( {(5.7s)}^{2} )$
this'll equal out to -159.2 meters.

our units equal out, so we know our answer is correct!
