A head on collision would be worse and it would actually be four times as worse since the speed is doubled and energy is a squared value so by far a head on collision with another car
Steering control. If you lose it, you will have no control whether the vehicle steers left or right. <span />
Answer:
19.62 m/s
34.335 m/s
1.75 m
Explanation:
v = Final velocity
u = Initial velocity = 0
a = g = Acceleration due to gravity = 
t = Time taken = 2 s
From the equations of linear motion we have

The speed of the object after 2 seconds is 19.62 m/s
t = 3.5 s

The velocity of the object when it strikes the ground is 34.335 m/s.

THe height from which the object was dropped is 1.75 m.
Remember that sound intensity decreases in inverse proportion to the distance squared. So, to solve this we are going to use the inverse square formula:

where

is the intensity at distance 2

is the intensity at distance 1

is distance 2

is distance 1
We can infer for our problem that

,

, and

. Lets replace those values in our formula to find

:





dB
We can conclude that the intensity of the sound when is <span>3 m from the source is
30 dB.</span>
