Answer:
C.
Explanation:
The acceleration of an object can be found using the equation:
where
v is the final velocity
u is the initial velocity
t is the time it takes for the velocity to change from u to v
In this problem:
u = 30 m/s is the initial velocity of Angelica
v = 84 m/s is the final velocity
t is the time
Substituting into the equation, we find the acceleration:
Answer:
<em>The volume of water is 3.5 cubic meter</em>
Explanation:
<u>Density </u>
The density of a substance or material is the mass per unit volume. The density varies with temperature and pressure.
The formula to calculate the density of a substance of mass (m) and volume (V) is:
We are given the density of water as .It's required to find the volume of m=3,500 kg of water. Solving for V:
The volume of water is 3.5 cubic meter
The average power output is the ratio between the work done to compress the spring, W, and the time taken, t:
(1)
The work done is equal to the elastic energy stored by the compressed spring:
where
is the spring constant and 
is the compression of the spring. If we substitute the numbers, we find:
And now we can use eq.(1) to calculate the average power output:
The work done is equal to the elastic energy stored by the compressed spring:
where
And now we can use eq.(1) to calculate the average power output:
