Given Information:  

Radius = r₁ = 150 m

Radius = r₂ = 73 m

Maximum speed = v₁ = 28.0 m/s

Required Information:  

Maximum speed = v₂ = ?

Answer:

Maximum speed v₂ = 19.53 m/s

Explanation:

The maximum acceleration of the truck is

a = v²₁/r₁

a = 28²/150

a = 5.226 m/s²

Now if we change the radius to r₂ = 73 m

Then the maximum speed of the truck is

v₂ = √a*r₂

v₂ = √5.226*73

v₂ = 19.53 m/s

So the speed of the truck is decreased when the radius of curve is decreased.

Explain the statement: “Cells are the basic units of structure and function in living things.”
babymother [125]

All living things are made up of cells.  Each cell's individual function helps the organism collectively function.  They are the most basic as they can be self-contained.  And there is no other particle smaller that can function on it's own.

Which example has the least kinetic energy
Stells [14]

Answer:

D

Explanation:

Let’s calculate the kinetic energy for all of the choices.

a. (1/2)(100)(100)^2 = 50(10000)=500,000

b. (1/2)(100)(1)^2 = 50

c. (1/2)(10)(100)^2 = 5(10000) = 50,000

d. (1/2)(1)(1)^2 = 0.5

We can see that (d) has the least kinetic energy.
