Answer:

KE=48J

Explanation:

You use the equation:

KE=1/2mv^2

KE=1/2(1.5kg)(8.0m/s)^2

KE=48J

Given : A toy plane has a mass of 1.5kg . It is flying in air at a speed of 8m/s .

To Find : The Kinetic energy of the plane .

Solution : The mass of the toy plane is 1.5kg and Velocity is 8.0 m / s . So we know the formula to find the kinetic energy as ,

\boxed{\red{\bf Energy_{Kinetic}=\dfrac{1}{2}mv^2}}

On substituting the respective values,

⇒ KE = ½mv².

⇒ KE = ½ × 1.5 kg × (8 m/s)².

⇒ KE = ½ × 1.5 kg × 64m²/s² .

⇒ KE = 48 J .

Anastasy [175]

Answer: 3.142656 × 10^16 feet

Explanation: Given that the

Speed = 982,080,000 ft/s, and

Time = 32,000,000 seconds

The formula for speed is:

Speed = distance/ time

Make distance the subject of formula

Since the time is second in one year and speed is ft/s, substitute both into the formula

Distance = speed × time

distance = 982,080,000 × 32,000,000

Distance = 3.142656 × 10^16 feet.

The distance of one light year in feet is 3.142656 × 10^16

You move a 25 N object 5 meters. How much work did you do ?
olga55 [171]
The answer is 125 Joules

The first thing to take note of is the work equation: W=F×D

Since we already have our force and our distance that will help make this problem easier.

So, W=25*5

W=125

Therefore, our answer is 125 Joules since work is measured in joules

Hope this helped!! :)
