Probably because of the drag coefficient and the density of the liquid.
To solve this problem we will apply the linear motion kinematic equations. From the definition of the final velocity, as the sum between the initial velocity and the product between the acceleration (gravity) by time, we will find the final velocity. From the second law of kinematics, we will find the vertical position traveled.
Here,
v = Final velocity
= Initial velocity
g = Acceleration due to gravity
t = Time
At t = 4s, v = -30m/s (Downward)
Therefore the initial velocity will be
Now the position can be calculated as,
When it has the ground, y=0 and the time is t=4s,
Therefore the cliff was initially to 41.6m from the ground
Answer:
The velocity is
Explanation:
From the question we are told that
The mass of the bullet is
The initial speed of the bullet is
The mass of the target is
The initial velocity of target is
The final velocity of the bullet is is
Generally according to the law of momentum conservation we have that
