Answer:
27,000 m
450 m/s
Explanation:
Assuming the initial velocity is 0 m/s:
v₀ = 0 m/s
a = 15 m/s²
t = 60 s
A) Find: Δy
Δy = v₀ t + ½ at²
Δy = (0 m/s) (60 s) + ½ (15 m/s²) (60 s)²
Δy = 27,000 m
B) Find: v_avg
v_avg = Δy / t
v_avg = 27,000 m / 60 s
v_avg = 450 m/s

An athlete produced 840 watts of power in 0.6 seconds. And will produce 504 joule of work did this individual perform during the exercise.
<u>Solution:</u>
we know that power is the work done completed in a given interval of time.
Power = 
also, Work = Power × Time
Work = 840 × 0.6 = 504 joule
What is Power?
- The quantity of work that can be accomplished in a certain amount of time is measured by power.
- Power is expressed in joules per second (J/s) this is because work is denoted by the symbol J and time by the symbol s.
- This is the watt, which is also known as the power unit in SI (W). One joule of labor per second is equal to one watt.
- The number of watts that a device uses is indicated on labels for lightbulbs and other small appliances like microwaves.
- A force must be applied in order for work to be completed, and there must also be motion or displacement in the force's direction.
- The amount of force multiplied by the distance moved in the force's direction is known as the work done by a force acting on an item. Work has no direction and only magnitude. Work is a scalar quantity as a result.
