Wind Energy is the kind of energy will Cassie uses to power the boat.
What is wind energy?
The method of producing electricity using air or wind currents that naturally occur in the earth's atmosphere is known as wind energy (or wind power). Electricity is produced by modern wind turbines that harness the kinetic energy of the wind. Wind passing across the turbine's blades is the initial step.
What is the major problem with wind energy?
Wind energy has the potential to have negative environmental effects, including the possibility of reducing, fragmenting, or deteriorating habitat for wildlife, fish, and plants, as with all energy supply choices. Furthermore, flying animals like birds and bats may be harmed by turbine blades in operation.

2: Fusion occurs constantly on our sun.When nuclei fuse create a heavier nuclear and produce a little leftover energy in the process
Answer:
a) 3.6 sec
b) 17.7 m/s
c) 17.7 m/s
d) 63.6 m
Explanation:
y = (25sin45)t - 4.9t^2 =17.7t - 4.9t^2
a) to find hang time set y = 0
4.9t^2 = 17.7t or t = 3.6 sec
b) vx = 25cos45 = 17.7 m/s
c) vy = 25sin45 = 17.7 m/s
d) To find the range R, use the results in (a) and (b) into the equation R = vxt:
R = (17.7 m/s)(3.6 sec) = 63.6 m
Answer:
Explanation:
Using Newton's second law:
Where 
is the force applied on the object, 
is the mass of the object, and 
is the acceleration.
In this case we need the acceleration, so we clear for :
we know that the force is: 
, and the mass: 
so the acceleration:
the acceleration of the block is:
