Answer:
The Kinetic energy of the Cheeto truck = 130,500 J
Explanation:
The Formula for Kinetic energy is
K.E = 1/2 x M x V^2
So in this Situation Mass(M) is 290kg
Velocity (V) is 30 m/s
Inputting these values into our equation gives us
K.E = 1/2 x 290 x 30^2
30 times 30 = 900
So K.E = 1/2 x 290 x 900
Simplifing this we get : K.E = 290 x 450
So K.E = 130,500 Kgm^2/s^2
Now the unit's Kgm^2/s^2 scientific name is Joule and symbol (J).
So K.E = 130,500 J
P.S: Oh man, now I have a craving for some Cheetos!

<h3>State Hooke's law?</h3>
Hokes's law states that, as long as the elastic limit of a body is not exceeded, the extension of the body is directly proportional to its force applied . Mathematically, we can write the Hooke's law as;
F = Ke
F = force applied
K = force constant
e = extension
Now;
F = 6N
K = ??
e = 33cm or 0.33 m
Thus
K = F/e
K = 6N/0.33 m
K = 18.18 N/m

Answer:
Explanation:
given,
diameter of inlet = 11.2 cm
r₁ = 5.6 cm
r₁ = 0.056 m ∵ 1 cm = 0.01 m
speed of inlet = 5 m/s
diameter of outlet = 17.5 cm
r₂ = 8.75 cm
r₂ = 0.0875 m ∵ 1 cm = 0.01 m
speed of outlet = ?
using continuity equation
A₁ v₁ = A₂ v₂
π r₁² v₁ = π r₂² v₂
Velocity of liquid at the outlet of the tube is equal to 3.2 m/s
