it wont let me send it with my drawing
D=(1/2) x at^2. d=(1/2)(4)(20)^2. 2(400)=800 m. In kilometers, the answer is 0.8 km. A. You're welcome. ;)
The youngest age that this person can be and legally operate a boat powered by a motor of more than 35 hp will be 12 years of age.
<h3 /><h3>What is electric power?</h3>
It is the rate of the electric work done. Its unit is the watt. Horsepower is the unit of power.
A person under the age of 12 may only legally operate a boat with a motor that has more than 6 horsepower but no more than 35 horsepower
if they meet two requirements: they have a boating safety certificate, which they must have on board; and they are being closely watched by an adult who is at least 16 years old.
Hence the youngest age that this person can be and legally operate a boat powered by a motor of more than 35 hp will be 12 years of age.

Answer:
F = 5000 [N] or 5 [kN]
Explanation:
In order to solve this problem we must take into account Newton's second law, which tells us that the sum of all forces applied on a body must be equal to the product of the mass of the body by its acceleration.
F = m*a
where:
F = force [N]
m = mass = 1000 [kg]
a = acceleration = 5 [m/s^2]
F = (1000*5)
F = 5000 [N] or 5 [kN]
To solve this problem, we must take two important steps. First we will convert all the given units, to international system. Later we will define the torque, which is given as the product between the radius of application of the force and the Force acting on the body. Mathematically the latter is,
Here,
r = Radius
F = Force
Now the units,
Replacing,
Therefore the torque that the muscle produces on the wrist is
