Answer:
Distance traveled during this acceleration will be 6950 m
Explanation:
Wear have given maximum speed tat will be equal to final speed of the car v = 278 m/sec
Constant acceleration
As the car starts initially starts from rest so initial velocity of the car u = 0 m/sec
From third equation of motion
Putting all values in equation
s = 6950 m
So distance traveled during this acceleration will be 6950 m
<h2>Answer:</h2><h2>The acceleration of the meteoroid due to the gravitational force exerted by the planet = 12.12 m/
</h2>
Explanation:
A meteoroid is in a circular orbit 600 km above the surface of a distant planet.
Mass of the planet = mass of earth = 5.972 x Kg
Radius of the earth = 90% of earth radius = 90% 6370 = 5733 km
The acceleration of the meteoroid due to the gravitational force exerted by the planet = ?
By formula, g =
where g is the acceleration due to the gravity
G is the universal gravitational constant = 6.67 x
M is the mass of the planet
r is the radius of the planet
Substituting the values, we get
g =
g = 12.12 m/
The acceleration of the meteoroid due to the gravitational force exerted by the planet = 12.12 m/
