Answer:
Identify the name of the individual, group or institution that created the website. A reliable website should clearly state the name of its creator. Generally, websites created by government institutions (.gov) and educational institutions (.edu) are considered more reliable.
Answer:
15.6m/s
Explanation:
V1=
because the derivate of the position is the velocity
V1=12t+3
V2=20+
-8t because the integral of the acceleration is the velocity
V2=
V1=V2 to see when the velocities of particles match
12t+3=20-4t^2
4t^2+12t-17=0 we resolve this with 
and we take the positif root
t=1.05 sec
if we evaluate the velocity (V1 or V2) the result is 15.6m/s
Answer:
Explanation:
The complete question is here.
A spring is compressed between two objects with unequal masses, m and M, held together. The objects are initially at rest on a horizontal friction less surface. When released, which of the following is true?
a) Kinetic energy is same as before being released
b) The total final kinetic energy is zero.
c) The two objects have equal kinetic energy.
d) The speed of one object is equal to the speed of other.
e) The total final momentum of two objects is zero.
So option e) the total final momentum of two objects is zero.
<span>Frederick Winslow Taylor laid down the fundamentals of the scientific managament. The scientific management methods optimized the way tasks were performed, improved economic efficiency, especially labor productivirty and simplified the jobs. The main benefit of this theory of management was that it encouraged workers to create goods more quickly and efficienty. (D)</span>
