First of all we state the formula
Power=work done/time
we can rearrange this formula as well
work done=power x time
Since the SI unit of time is in seconds we change the minutes to seconds
2mins= 60x2 = 120 seconds
Using our formula (work done=power x time) we simply put in the values
work done = 4500 x 120
work done = 540,000J
Answer:
4 m/s
Explanation:
From the question given above, the following data were obtained:
Maximum range (Rₘₐₓ) = 1.6 m
Acceleration due to gravity (g) = 10 m/s²
Initial velocity (u) =?
The initial velocity of the projectile can be obtained as follow:
Rₘₐₓ = u² / g
1.6 = u² / 10
Cross multiply
u² = 1.6 × 10
u² = 16
Take the square root of both side
u = √16
u = 4 m/s
Therefore, the velocity of the projectile is 4 m/s

The correct answers are as follows:
1. D [CONTEXT]
The acronyms AUDIENCE stands for following:

I: Interest
E: Enviroment
N: Needs
C: Context
E: Expectation
The acronyms is used in speech presentation to consider and analyse the audience needs so that a speaker will be able to satisfy these needs.

Brainstorming is the process by which ideas are generated by a group while free association usually involves only one person and it has to do with resolving inner conflicts and contradictions.
5. FREE ASSOCIATION
Free association is a method developed by Sigmund Freud. It is a psychoanalytical method which he used to help his patients to learn more about what they are thinking and feeling. This method bring to the fore the unconscious and the repressed thoughts of the patients.
