The vehicle accelerates at 2.648 m/s².
We have:
Initial velocity, u = 50 miles per hour = 22.352 m/s
final velocity, v = 80 miles per hour = 35.762 m/s
Time, t = 5 seconds
The time in hours is:
t = 5 seconds
Now, the acceleration of the car can be calculated using the formula:
v = u + at
35.762 = 22.352 + a(5)
a(5) = 30
a = 2.682 m/s²
From the calculations above, the acceleration of the car is 2.682 m/s².

Answer:
m = 7.48 kg
Explanation:
force (f) = 11,500 N
length of barrel (s) = 1.7 m
angle above the ground = 49.3 degrees
acceleration due to gravity (g) = 9.8 m/s^{2}
initial velocity (u) = 0 m/s
final velocity (v) = 72.3 m/s
mass (m) = ?
force = mass (m) x acceleration (a)
acceleration (a) = force / mass (m)
acceleration (a) = 11500 / m
applying the equation of motion 
, we can get the mass
5227.3 = 0 + 
m = 
m = 7.48 kg
Explanation :
(1) Big bang : (1) The most accepted theory on the origin of the universe.
This theory shows the expanding of the universe from high density and high-temperature states.
(2) Steady state : (3) All is the same and will always stay the same.
Steady state means that the properties of any system remain the same always.
(3) Oscillating universe : (4) Agrees with the big bang theory but insists the universe expanded much quicker.
Oscillating universe theory is the result of big bang theory.
(4) Inflation Choices : (2) it's like an inflating and deflating balloon that never stops.
In cosmology, cosmic inflation or deflation is just the expanding and contraction of the universe.
So, the statements and the choices are related as:
(1)-(1)
(2)- (3)
(3)-(4)
(4)-(2)
Answer: Visible light makes up just a small part of the full electromagnetic spectrum. Electromagnetic waves with shorter wavelengths and higher frequencies include ultraviolet light, X-rays, and gamma rays.
