A cheetah is walking at 5.0m/s when it sees a zebra 35m away. What acceleration would be required for the cheetah to reach 25.0

m/s in that distance?

Answer:

Acceleration, a=8.57\ m/s^2

Explanation:

Given that,

Initial speed of the Cheetah, u = 5 m/s

Distance covered, s = 35 m

Final speed of the cheetah, v = 25 m/s

We need to find the acceleration required for the cheetah to reach its final speed. The formula is as follows :

a=\dfrac{v^2-u^2}{2s}

a=\dfrac{(25)^2-(5)^2}{2\times 35}

a=8.57\ m/s^2

So, the acceleration of the cheetah is 8.57\ m/s^2. Hence, this is the required solution.

In order to create a charged object, you need to ________.
Brums [2.3K]
In order to create a charged object you need to transfer electrons either away or to the object by induction, conduction, or friction

Induction is without contact(like bringing a charged object to a electroscope charges the leaves at the bottom)
Conduction is with contact(like the previous answer, wore touching transfers the charge from a source to the object)
Friction(rubbing a balloon on wool)

Hi guys can you help me with finding advantages with nuclear power?
soldier1979 [14.2K]

Answer:

Low-cost energy. Although building nuclear power plants has a high initial cost, it’s relatively cheap to produce energy from them and they have low operating costs.

Reliable. One of the biggest benefits of nuclear energy is that it is a reliable power generation source.  

Zero carbon emissions. Nuclear power reactors do not produce any carbon emissions.  

Promising future energy supply.
