Answer:
6.9m/s
Explanation:
Given parameters:
Acceleration of the object = 4m/s²
Distance = from x; 2m to x; 8m
Unknown:
Average velocity = ?
Solution:
From the given parameters, we use the right motion equation to solve the problem.
v² = u² + 2aS
v is the final velocity
u is the initial velocity
a is the acceleration
S is the distance covered
Distance = 8m - 2m = 6m
Initial velocity = 0m/s
The final velocity gives us the average velocity in this problem;
v² = 0² + (2 x 4 x 6) = 48
v = √48 = 6.9m/s
Answer:
oone side at a time would be hot and the other oone
Explanation:
One side will be hot and the other cold no in-between
Alkali metals : sodium , potassium
alkaline earth : magnesium , calcium
the rest are transition elements... i don't know about "inner transition"
Explanation:
It is given that,
The velocity of a particle is given by :
Where
v is in m/s and t is in seconds
Let a is the acceleration of the object at time t. So,
When a = 0
t = 2.5 s
a is zero at t = 2.5 s. Velocity, 
v = -75 m/s
Since, 
, s is the distance travelled
At t = 2.5 s, 
s = −83.34 m
Hence, this is the required solution.
