Answer:1. INCREASE 2. DECREASE 3. DECREASE
Explanation:
You need the kinematic equation for distance as a function of acceleration:
![d = [v(initial) *t] + 0.5a*t^{2}](https://tex.z-dn.net/?f=d%20%3D%20%5Bv%28initial%29%20%2At%5D%20%2B%200.5a%2At%5E%7B2%7D)
where a = gravitational acceleration 9.8m/s^{2}
v(initial) = starting velocity
t = time of fall
if the stone started at rest then v(initial) = 0 making the equation simply

Let me know if you still need further help :)
The easy answer is lighting.
In order to find the speed per minute you will have to divide the two numbers together. You need to do 36/5.4 so the answer will be around 6.7 feet per minute.
<span>This problem is solved by the equation of motion:
x = x0 + v0*t + 1/2*a*t^2,
Here x0 = 0, v0 = 40ft/sec and a = -5 ft/s^2, we need to solve for t:
v = v0 + a*t, solve how long does it take to stop: 0 = v0 + a*t --> a*t = -v0 --> t = -v0/a
-- > 40/5 = 8 seconds to stop.
In this time, the car travels x = 0 + 40*8 + 0.5*-5*8^2 ft ~ 160 ft.
Answer: The car travels 160 ft.</span>
