What is Wayne’s power?
Answer in units of W.

dont do it just fail

Power=Fx * d/t = 70.9*Cos48 * 19.9/4.3 =

Note: J/s = Watts.

To find Wayne's power, we can use the formula for power:

Power (P) = Force (F) * Velocity (V)

First, let's find the horizontal component of the force exerted by Wayne, which is given by:

Force (F_horizontal) = Force (F) * cos(angle)

Here, the angle is given as 48 degrees. We need to convert it to radians:

Angle (in radians) = 48 degrees * (π / 180 degrees)

Next, let's calculate the horizontal component of the force:

F_horizontal = 70.9 N * cos(48 degrees)

Now, let's find the work done by Wayne, which is given by:

Work (W) = Force (F_horizontal) * Distance (d)

Here, the distance is given as 19.9 m.

Work (W) = F_horizontal * 19.9 m

Now, we can calculate Wayne's power:

Power (P) = Work (W) / Time (t)

Here, the time is given as 4.3 s.

Power (P) = Work (W) / 4.3 s

By substituting the values we calculated earlier:

Power (P) = (70.9 N * cos(48 degrees) * 19.9 m) / 4.3 s

Calculating this expression will give us the value of Wayne's power in watts.

To find Wayne's power, we need to use the formula for power:

Power = Force × Distance ÷ Time

1. Step 1: Calculate the horizontal component of the force.
The force applied by Wayne is 70.9 N, and the angle with the ground is 48°. To find the horizontal component of the force, we need to calculate the cosine of the angle.

Horizontal component of the force = Force × cos(angle)

Horizontal component of the force = 70.9 N × cos(48°)

2. Step 2: Calculate the work done.
The work done is equal to the force multiplied by the distance.

Work = Force × Distance

Work = Horizontal component of the force × Distance

Work = (70.9 N × cos(48°)) × 19.9 m

3. Step 3: Calculate the power.
The power is equal to the work done divided by the time.

Power = Work ÷ Time

Power = [(70.9 N × cos(48°)) × 19.9 m] ÷ 4.3 s

Now, let's calculate Wayne's power using these formulas.
