Answer:
v = 1/3 m / s = 0.333 m / s
in the direction of the truck
Explanation:
The average speed is defined by the variation of the position between the time spent
v = Δx / Δt
since the position is a vector we must add using vectors, we will assume that the displacement to the right is positive, the total displacement is
Δx = 20 - 15 +20
Δx = 25 m
therefore we calculate
v = 25/75
v = 1/3 m / s = 0.333 m / s
in the direction of the truck
C i’m pretty sure but don’t take me as your first answer i just need to answer a question to ask one.
Answer:
962291.57928 m²
Explanation:
= Pressure = 
(full reflection)
I = Intensity = 
P = Power = 
c = Speed of light = 
M = Mass of Sun = 
m = Mass of ship = 1500 kg
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
Force of radiation is given by
This force will balance the gravitational force as stated in the question
The area of the must be 962291.57928 m²
Given that the arc length is:
s = ∫ √[1² + (dy/dx)²] dx
<span>So arc length between the two points is then: </span>
<span>s = 2*20sinh(x/20)
= 40sinh(x/20) </span>
<span>The straight distance between the two points is : d = 2x </span>
<span>So, x = d/2.
= 40/2
= 20 m </span>
<span>Plug this into the arc length equation to get:
s = 40sinh[20/20)]
=40* ½ (e - 1/e) </span>
<span> = 47 m</span>
its the 3rd one kinetic energy increases as speed increases
