The equation
describes the relationship of he distance traveled and the time elapsed as one object travels a specified distance. This means that when t is 2 then d is 80. You know that a car is still in the air when the distance is a positive number and zero. The equation only holds true when t is at 0 to 3.

Complete Question
A skier leaves a ski jump with a horizontal velocity of 29.4 m/s. The instant before she lands three seconds later, the magnitudes of the horizontal and vertical components of her velocity are: Group of answer choices
A 29.4 m/s; 29.4 m/s.
B 41.6 m/s; 41.6 m/s.
C 29.4 m/s; 41.6 m/s.
D 0; 29.4 m/s.
E 29.4 m/s; 0.
Answer:
Correct option is A
Explanation:
From the question we are told that
The horizontal velocity is
The time taken for the jump is
The velocity along the vertical axis is
substituting values
During the jump the horizontal velocity remains the same as there was a direction change
So the correct option is A
Answer:
(a)
(b)
(c)
Explanation:
(a) The total mechanical energy of the system is conserved.
(b) The conservation of energy states
(c) As explained in part (a) the total mechanical energy of the system is equal to the initial kinetic energy, since the potential energy of the system at that point is zero.
