Answer:
The distance between the camera and the rock is 836.6 cm
Explanation:
A right triangle is formed where the hypotenuse (h) is the distance between the rock and the camera. One of the leg (l) is the distance between the camera and the surface. The angle between the hypotenuse and this leg is α = 90° - 13.69° = 76.31°. By definition:
cos α = adjacent/hypotenuse
cos(76.31) = 198.0/h
h = 198.0/cos(76.31)
h = 836.6 cm
Answer:
<h2>12 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula

f is the force
m is the mass
From the question
f = 6000 N
m = 500 kg
We have

We have the final answer as
<h3>12 m/s²</h3>
Hope this helps you

Answer:
1) Skid
2)<u> </u>Rocking
3) Oversteer situation
4) Controlled breaking
5) Overdriving headlights
6) Hydroplaning
7) Understeer situation
Explanation:
1) A <u>skid</u> results when a vehicle loses part or all of its grip on the road
2)<u> Rocking</u> is a technique that can be applied when trying to move your vehicle out of deep snow
3) The action of vehicle's rear end sliding out to a side is called an <u>oversteer situation</u>
4) <u>Controlled breaking</u> is a technique of reducing your speed as quick as possible while maintaining control of your vehicle
5) Driving at a speed where the stopping distance of your vehicle is longer than the distance you can see with your headlights is called <u>overdriving headlights</u>
6) <u>Hydroplaning</u> occurs when a tire loses road surface contact and rises on top of water
7) It is an <u>understeer situation</u> when your front tires begin to plow and your vehicle is not responding or not responding as quickly as it should, to a steering point
Answer:
a = 2.77 [m/s²]
Explanation:
To solve this problem we must use the following equation of kinematics.

where:
Vf = final velocity = 19 [m/s]
Vo = initial velocity = 44 [m/s]
a = acceleration [m/s²]
t = time = 9 [s]
Note: The negative sign in the above equation means that the train is decreasing its velocity.
19 = 44 - a*9
9*a = 44 -19
a = 2.77 [m/s²]
