Answer:
After it finishes speeding up, the car goes 72 [m]
Explanation:
To solve this problem we must first understand the graphics. It is clear that in the last 6 seconds, that is, from the fourth to the tenth second, the car moves at a constant speed.
Therefore in this time interval, the car moves at a constant speed.
With the following equation of kinematics, we can calculate the distance traveled.
where:
x = final point [m]
x₀ = initial point [m]
v = constant velocity = 12 [m/s]
t = time = 6 [s]
Now replacing we have:
A is the best choice!!!!!!!
A - alpha as two protons and two neutrons have been released.
Gamma rays, x-rays, ultraviolet, infrared, microwaves and radio waves<span>. Together with visible light, all these </span>types<span> of radiation </span>make up<span> what we call the </span>electromagnetic spectrum<span> </span>
Answer:
The speed of the rain is
Explanation:
From the question we are told that
The initial speed and direction of the car is
The angle made with the horizontal is
The velocity of rain is
An illustrate of this question is shown on the first uploaded image
From the diagram we see that
