The force of friction is given in the scenario:
Force = 500 Newton
and the mass of the runner is 60 kg
To find the acceleration we need to use the relation between force, mass, and the acceleration of the object:

Where 'F' represents the force, 'm' represents the mass, and 'a' represents the acceleration.
Plugging the value of variables we get:

Solving for 'a' (acceleration) we get:
Newton/kilogram or meters/ second squared
So the acceleration of the runner is 8.33 meters/ second squared.
Answer:
13.6
Step-by-step explanation:
This is pythagoras theorem its c2 = a2+b2
13 squared + 4 squared is 185
the square root of 185 13.601
then rounded is 13.6
Answer:
64
mm² or approximately 201.06 mm²
Step-by-step explanation:
If the diameter is 16 mm, the radius will be 8 mm.
Use the circle area formula, A =
r², where r is the radius. Plug in 8 as r:
A =
r²
A =
(8²)
A = 64
So, the area of the circle is 64
mm² or approximately 201.06 mm²
Answer:
Get rid of distractions that makes you procrastinate.
Step-by-step explanation:
Focus doing your practices. To focus, you need to get rid of any distractions that make you procrastinate.
As an example, if it's your phone/social media. Try to make it silent/put it away from you when you're going to do your practices. (recommended to give to parents or put in other room until you finish your works)
This is just my suggestion. It works for some people.
2/8 is the answer because if you do 3-1 it would equal 2 and then you would put 2 over eight. You can even simplify it to 1/4 because 2 and 8 can both be divided by 2.
