Answer:
Part a)
Part b)
Part c)
Explanation:
Part a)
As we know that ball will reach at maximum height at
t = 3 s
now we will have
now we have
Now maximum height above ground is given as
Part b)
Height of the fence is given as
Part c)
As we know that its horizontal distance moved by the ball in 5.5 s is given as
now total time of flight is given as
so range is given as
so the distance from the fence is given as
In order to get the propoerty of work you need to use the following formula
<span>work = force times distance
</span>replacing data you will get:
W = (1.500) (3)
W = 4.500 NM
The answer should be in NM. So it will be 4500 NM againts the force of gravity
Because less energy is being wasted. non-renewable resources will last longer.
the cost is kept lower. hope it helps :)
There are 3 different types of energy. These 3 are fossil fuel, nuclear energy, and renewable energy. Most electricity is generated by ether wind, solar, or thermoelectric. Thermoelectric produces energy by burning coal,natural gas, and oil in a boiler.
