Answer:
Explanation:
Hello,
In this case, since the acceleration in terms of position is defined as its second derivative:
The purpose here is derive x(t) twice as follows:
Thus, the acceleration turns out 4.8 meters per squared seconds.
Best regards.
Answer:
Explanation:
let t be time since the second diamond is released
a) y = ½g(t + 1)²
b) y' = ½g(t)²
c)
25 = ½g(t + 1)² - ½gt²
25 = ½g(t² + 2t + 1) - ½gt²
25 = ½gt² + gt + ½g - ½gt²
25 = g(t + ½)
t + ½ = 25 / g
t = (25 / g) - ½
t = (25 / 9.8) - ½
t = 2.05102... ≈ 2.1 s
Answer:
2.41m/s
Explanation:
Given parameters:
Initial velocity = 1.5m/s
Acceleration = 0.275m/s²
Distance = 6.45m
Unknown:
Final velocity = ?
Solution:
To solve this problem, we apply the kinematics equation below:
v² = u² + 2aS
v is the final velocity
u is the initial velocity
a is the acceleration
S is the distance
v² = 1.5² + (2 x 0.275 x 6.45)
v = 2.41m/s
Fundamental can not be broken down to anything simpler ( Kg, m , s, etc)
Derived can be broken down to simpler, fundamental units
Who created the theory of general relativity?:
The answer would be: Albert Einstein.
Albert Einstein developed the general relativity theory (gravitation).
The year he developed the general relativity theory or (GR) was back in 1907 and 1915. Then many other contributions after 1915.
