Answer:
3.95979 m/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
Here 
Initial velocity of the puck should be 3.95979 m/s
Answer:
F = 132N
Explanation:
Let the pulling force be F
Given the mass of the barrel is 12 Kg and The acceleration is 1.2 m/
We know that Net Force = 
Now net force = F - mg
F - mg = ma
F = mg + ma
F = m(a+g) = 
Note that there will be a downward force acting on the body which is equal to mg
Answer:
Explanation:
For free body diagram see attached sheet .
W is weight of steel girder acting at the middle point of its length . T is tension in the cable .
OB = √ ( 12² - 2² )
= 11.83 m .
OC = 11.83 / 2 = 5.915 m
Taking moment of tension T and weight W about point O
W x OC = T x OB
22 x 5.915 = T x 11.83
T = 22 x 5.915 / 11.83
= 11 kN
Considering forces acting in vertical direction and equating forces in opposite direction
T + R = W
R = W - T
= 22 - 11 = 11 KN
So force of grinder on the ground = R
= 11 KN.
Answer:
2) Denotative meaning of a word or Denotation.
3) Connotative meaning of a word or Connotation.
4) Ethics and Culture.
Explanation:
2) Which meaning of a word refers to exactly what it is?
The denotative meaning of a word represents the explicit or the exact meaning of that word. Also called the denotation of the word.
3) Which meaning of a word includes what the word may represent?
The Connotative meaningof a word means something suggested or implied by a word. Also called the Connotation of the word.
4) What is the term used for society's tried and true rules that guide life?
Ethics refer to the rules and standards that guide the conduct of individuals; especially members of a societal body.
Culture is the total way of life of a society.
Hence, ethics amd culture both serve as the society's tried and tested rules that guide life.
Hope this Helps!!!
Answer:
A. A car can still be moving without acceleration when it has some velocity.
B. A car can come to a stop when moving itself when it has some de acceleration.
C.A ca can start at 0 m/s and speed up to 15 m/s when it has some acceleration.
Explanation:
A. since the car has no acceleration the velocity of the car would help it moving.
B. when the car is moving with some velocity but coming to a stop this is possible of and only if it has some de acceleration
C. since the speed of the car increases from 0 to 15 m/s acceleration is involved. If the speed was constant there would be no acceleration involved.
