Acceleration = ( final velocity - intial velocity ) / time
= (60-0)m/s / 3s
= 20 m/s2
the answer is a

Answer:
The mass of the fish is 18.1 kg.
Explanation:
Given;
weight of the fish, F = 108 N
extension of the spring by the given weight, x = 14 cm = 0.14 m
First, determine the elastic constant of the spring by applying Hook's law;
F = kx
where;
k is the spring constant
k = F/x
k = 108 / 0.14
k = 771.43 N/m
When the spring is stretched to 23cm, the mass of the fish is calculated as follows;
Therefore, the mass of the fish is 18.1 kg.
A point of a single dimension, a plane of two, and 3D involving the depth of the third dimension.
Explanation:
It is known that general formula to calculate the volume of a cone is as follows.
Volume of the cone =
and here, r =
So, V =
On putting the given values into the above formula we will calculate the value f h as follows.
V =
=
=
Now, we will differentiate w.r.t t as follows.
=
It is given that water here flows at a rate of 1.5 and h = 1.1 m.
1.5 =
1.5 =
= 0.888
= 0.9 m/min (approx)
Thus, we can conclude that the water level is rising at a rate of 0.9 m/min.
