The difference is two laws of motion.
Answer : Newton's first law of motion (also known as Law of Inertia) describes about the tendency of an object to resist change from its state of rest / motion / direction (inertia).
Whereas, Newton's third law of motion tells us that forces exists in pairs. It talks about the action & reaction forces, which are equal in magnitude but opposite in direction.
In this way, Newton's third law of motion is different from Newton's first law of motion.

The speed of the car is 75 km/h
Further explanation
These are the formulas that we have to remember before solving the problem.
Speed is the rate of change of distance.
v = speed ( m/s )
d = distance ( m )
t = time ( s )
Acceleration is the rate of change of velocity.
a = acceleration ( m/s² )
Δv = change in speed ( m/s )
t = time ( s )
Let us now tackle the problem!
Given:
distance = d = 150 km
time taken = t = 7200 s = 2 hours
Unknown:
velocity = v = ?
Solution:
The acceleration of the car is 0 m/s² because it travels with constant speed.
We could also plot the distance vs time graph as shown in the attachment.

Final answer:
The car's speed is 75 km/hour, as determined by dividing the total distance travelled (150 km) by the total time taken (2 hours).
Explanation:
To answer this question, we use the
formula for speed
, which is distance traveled divided by the time taken. Here, the distance travelled by the car is 150 km and the time taken is 7200 s (which is equal to 2 hours). Therefore, the speed will be 150 km divided by 2 hours, resulting in a speed of
75 km/hour
, stated to the correct number of significant figures.

Large astronomical bodies are round because at their formation, gravity acted as the force to bring all of the matter together to form the body. Since the gravity was acting from a point and bringing everything toward it, the final shape of the mass is spherical. Non-round bodies are mostly that shape because other bodies "modified" the landscape.

Answer:
E.) None of the above
Explanation:
Draw a free body diagram. There are two forces acting on the car. Normal force perpendicular to the road, and weight downward.
Sum of the forces perpendicular to the road:
∑F = ma
N − mg cos θ = 0
N = mg cos θ
Sum of the forces towards the center of the circle:
∑F = ma
N sin θ = mv²/r
mg cos θ sin θ = mv²/r
g cos θ sin θ = v²/r
v = √(gr cos θ sin θ)
Given r = 50 m and θ = 5°:
v = √(9.8 m/s² × 50 m × cos 5° × sin 5°)
v = 6.52 m/s
v = 14.6 mph
