The power is 
Explanation:
First of all, we need to find the acceleration of the car, which is given by
where
v = 60 mph = 26.8 m/s is the final velocity
u = 0 is the initial velocity
t = 10.0 s is the time
Substituting,
Now we can find the mass of the car by using Newton's second law:
where
F = 5300 N is the force applied
m is the mass
is the acceleration
Solving for m,
Now we can use the work-energy theorem, which states that the work done is equal to the change in kinetic energy of the car, to find the work:
And substituting,
Finally, we can find the power output of the car:
where
W is the work
t = 10.0 s is the time elapsed
Substituting,

If you can get the money, the laboratory to use, the experimental
equipment, and the people you need to work on it with you, then
curiosity is a fine, honorable, and perfectly good reason to go ahead,
do what you gotta do, follow your heart, satisfy your curiosity, and learn
new stuff.
Neither the Large Hadron Collider, nor the Mars Rover, nor the Hubble
Space Telescope, nor the New Horizons probe, was built to cure cancer.
Answer:

Answer:
The velocity is 
Explanation:
Given:
Force = 500N
Distance s= 0
To find :
Its velocity at s = 0.5 m
Solution:
Using the relation,
Now integrating on both sides
