Answer:
1531 m
Explanation:
The motion of the jet ski is an uniformly accelerated motion, so we can find the distance travelled by using the following suvat equation:

where
s is the distance
u is the initial velocity
t is the time
a is the acceleration
For the jet ski in this problem,

t = 35 s
u = 0 (it starts from rest)
Solving for s, we find the distance travelled:

the branch of mechanics concerned with the motion of objects without reference to the forces which cause the motion.
True because on side is heavier than the other
Answer: The height of the pile increasing is increasing at 
Explanation:
Given
Rate at which gravel is being dumped , 
=>Rate of increase of volume of cone=
If height of the cone at any instant is h then the diameter of cone is also h
Volume of cone , 
Now differentiate both sides w.r.t time(t)

Therefore at h = 9 ft

=>
Thus the height of the pile increasing is increasing at

Explanation:
uh I might be crazy but there is two ways to solve this a simple way and complexish first understand you are using kinematic equations all 4 are valid for this but you need to know which ones the best choice which is vf=vi + at this should solve for time i would do it for you but I find it better when you plug it in your self your learn much better
