Answer:
assuming you're looking for an expression, it would be written as "6x+3".
 
        
                    
             
        
        
        
The rate of deceleration is equal to 25 m/s / 6 s = 25/6 m/s^2. 
(a) The string should be angled in such a way that the horizontal acceleration is equal to 25.6 and the vertical acceleration is equal to gravitational acceleration. Using trigonometry,Angle from the vertical = arctan(25/6 / 9.8) = 23.03 degrees.
(b) Since the car is decelerating, one end of the string attached to the car is pulled back and because of the inertia of the object it is goes on the opposite direction and so the object moves toward the windshield.

Answer:
The time required is 15.97 second.
Step-by-step explanation:
Consider the provided information.
A skywalk is 90 feet beyond the canyon's edge and is 4080 ft above the canyon floor.
First find the distance between skywalk and canyon floor by using Pythagorean theorem.
Distance between skywalk and canyon's edge = 
Distance between skywalk and canyon's edge = 
Substitute h = 4080.99 in the provided formula.



Hence, the time required is 15.97 second.
