Answer:

Power  = 1600Watts

Explanation:

Power is given by the rate of energy expended or work done by a body (or object).

Power = \frac{Workdone}{time}

Where;

Workdone = Force x distance

=> Power = Force x distance / time   -----------------------(i)

<em>According to the question,</em>

Force = 8000N

distance = 4m

time = 20 s

<em>Substitute these values into equation (i) above</em>

=> Power = 8000 x 4 / 20

=> Power = 1600Watts

Therefore the  power of the tow truck is 1600Watts

. What is the velocity of a free-<br> falling object after 5 seconds?<br> (Use 10 m/s2 for gravity.)
Viefleur [7K]

Answer:

vf = 50 m/s

Explanation:

The equation for this kinematic problem is:

vf = vi + at

We are given:

a = 10m/s^2

vi = 0m/s

t = 5 sec

vf = ?

Solve for final velocity:

vf = 0 + 10(5)

vf = 50 m/s
