Acar is pulled with a force of 10,000 n. the car's mass is 1267 kg. but, the car covers 394.6 m in 15 seconds [a]what is the expected acceleration of the car from 10,000 n force? [b]what is the actual acceleration from the observed data of x and t? [c]what is the difference in accelerations? [d]what force caused this difference? [e]what is the magnitude and direction of the force that caused the difference in acceleration?

Part a)

Part b)

Part c)

Part d)

This difference in acceleration  is due to some frictional force on the surface.

Part e)

Explanation:

Part a)

As we know by newton's II law

here we know that

Now we have

Part b)

distance covered by the car

t = 15 s

now by kinematics we have

Part c)

Difference of acceleration is given as

Part d)

This difference in acceleration  is due to some frictional force on the surface.

Part e)

Now for magnitude of force is given as

d. air pressure decreases as altitude increases.

wavelength divides in half and speed stays the same.
