To solve this problem we will apply the concepts related to the kinematic equations of linear emotion. We will start from the definition of acceleration as the change of speed as a function of time. Later we will apply the second law of kinematics for which displacement is understood as a function of initial speed, time and acceleration. We will use the expressions given initially for acceleration as a function of velocity and we will obtain a system of equations that will allow us to find the initial velocity, and subsequently the acceleration
PART A)
Position is given as,
Replacing,
Reorganizing to find the initial speed
Replacing we have,
Therefore the speed of Antelope at first point is 5.23m/s
PART B)
The acceleration of the Antelope would be
Therefore the acceleration of the Antelope is
This is a matter of thought, so the father is probably more likely to slow down faster because the weighs more and gravity pulls him down to the friction of the ice more potently Thant the child. So, the father.
Answer:
C. has no effect on validity
Explanation:
Repeating your experiment has no effect on validity.
It doesn't matter how many times you repeat your experiment. You have to find the average outcome of each experiment you do.

The more energy a particle has the more it will move faster . If you take some cold solid material and add energy to it (heat it up) the particles in it will rattle around more. Usually at some point they will rattle so much that they break up the regular solid pattern and start sliding around as a liquid.
