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
Alfisols can be found in humid areas and semiarid areas. They are formed in forest and savanna vegetation. They are very fertile and productive soils. These soils contains high concentrations of nutrient that are cations like calcium, magnesium, potassium and sodium.
A chemical change is when a substances chemical properties change, for example, baking a cake. A physical change is when the appearance/odor/texture etc. change, for example, ice melting
