The average power created by the force F is 1440 W

\texttt{ }

<h3>Further explanation</h3>

Newton's second law of motion states that the resultant force applied to an object is directly proportional to the mass and acceleration of the object.

\large {\boxed {F = ma }

F = Force ( Newton )

m = Object's Mass ( kg )

a = Acceleration ( m )

Let us now tackle the problem !

\texttt{ }

<u>Given:</u>

magnitude of horizontal force = F = 600 N

acceleration of sled = a = 0.08 m/s²

elapsed time = t = 1 min = 60 s

<u>Asked:</u>

average power by the force F = ?

<u>Solution:</u>

P = W \div t

P = ( F d ) \div t

P = F ( \frac { 1}{2} at^2 ) \div t

P = \frac{1}{2} F a t

P = \frac{1}{2} \times 600 \times 0.08 \times 60

P = 1440 \texttt{ W}

\texttt{ }

F = 600 N, the applied force
a = 0.08 m/s², the acceleration
t = 1 min = 60 s, the duration

Calculate the distance traveled.
s = (1/2)at²
   = 0.5*(0.08 m/s²)*(60 s)²
   = 144 m

Because the force remains constant, the work done is
W = f*s
    = (600 N)*(144 m)
    = 86400 J

The average power is
Pavg = (86400 J)/(60 s) = 1440 W

Answer:  1440 W

Viktor [21]

Answer:

It will have aim at a point "below" the insect.

From the insect's point of view, the fish will appear to be shallower than it actually is because a ray of light from the insect to the fish will be bent "towards" the normal when the ray enters the water

A box of mass 7.7 - kg is accelerated from rest across a floor at a rate of 2.6 m/s2 for 18.5 s. Find the net work done on the b
mixer [17]

Answer:

Explanation:

The net work will change the kinetic energy

W = ½mv² = ½m(at)² = ½ma²t²

W = ½(7.7)2.6²(18.5²) = 8907.3985 = 89 kJ

A 100 kg cyclist travels at 4.5 m/s. A 50 kg gorilla is dropped straight down onto her. What is the new speed of the system?
krek1111 [17]

Mass of cyclist = 100 kg

Mass of gorilla = 50 kg

Initial speed = 4.5 m/s

Let Final speed = s

100 x 4.5 = (100 + 50) x s

450 = 150s

S = 450/150

S = 3

The new speed is 3m/s
