Answer:
The work and energy is inter- related because if we are energetic then only we are able to work.
People who are weak and not energetic cannot work continuously.

Answer:
Left
Explanation:
The force is applied opposite of the acceleration.
Answer:
a. Time=25seconds
b.distance=1041.67m
Explanation:
a.The equation for 
in terms of m/s is 
after conversion.
To find when speed reaches 300km/hr=83.33m/s, we find 
and solve for 
b. From a, above we already have our t=25seconds as the time it takes before the plane is airborne.
#To find distance travelled in that time , we substitute for
in our distance equation:
Hence the distance of the plane before it gets airborne is 1041.67m
We need to considerate only the horizontal component of the motion of the toy car.
The formula for the distance in a decelerated motion is:
s = s₀ + v₀·t - 1/2·a·t²
where:
s₀ = initial position = 0
v₀ = initial velocity = 1.21 m/s
t = time elapsed = 0.342 s
a = deceleration = 0.131 m/s²
Plugging in numbers:
s = 0 + 1.21×0.342 - 0.5×0.141×(0.342)²
= 0.406 m
Hence, the toy car traveled a distance of about 41 cm.
