Answer:

Average Power =581.6W

Explanation:

Power is the rate of doing work.

Power =\frac{W}{t}

W = F*S

Power =\frac{F*S}{t}

Where F is force, S is distance, t is time

F= weight of the student= 727N

S=12m,    t= 15sec

Power =\frac{727*12}{15}

Power =581.6W

A 6,000N is applied to a formula one car that weighs 500kg. What is the car's acceleration?
Vesna [10]

Answer:

<h2>12 m/s²</h2>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m}  \\

f is the force

m is the mass

From the question

f = 6000 N

m = 500 kg

We have

a =  \frac{6000}{500}  =  \frac{60}{5}  = 12 \\

We have the final answer as

<h3>12 m/s²</h3>

Hope this helps you
