Answer:
the gravitational force between the satellite and the planet is 32.4 * 10³N
Explanation:
It is given that,
Mass of the satellite, m = 6500 kg
Speed of the satellite, v = 6.7 × 10³ m/s
distance to the center of the planet = 9 × 10⁶m
Let F is the magnitude of the gravitational force exerted on the satellite by the planet. The centripetal force is equal to the gravitational force. It is equal to :
= 32.4 * 10³N
the gravitational force between the satellite and the planet is 32.4 * 10³N
Answer:
The skidding distance would be doubled
Explanation:
When the truck applies the brakes and slows down, its motion is a uniformly accelerated motion, so its skidding distance can be found by using the suvat equation
where
v = 0 is the final velocity (zero since the truck comes to a stop)
u is the initial velocity
a is the acceleration
s is the skidding distance
The acceleration can also be written as
where F is the force applied by the brakes and m the mass of the truck. Substituting into the previous equation,
We see that the skidding distance is proportional to the mass: therefore, if the mass of the truck is doubled, the skidding distance will double as well.
Answer:
Silicon was touted as the revolutionary material that can do wonders in the tech industry.
Explanation:
Answer: 45000 m/s^2
Explanation:
First, we know:
Bullet's Initial Velocity (Vo) = 0 m/s
Distance Travelled (D) = 1 m
Final Velocity (Vf) = 300 m/s
We need to know the bullets acceleration to reach the final velocity on that distance. Because the bullet stars from rest, his Initial Velocity is equal to zero.
We dont know on how much time it takes for the bullet, but we know the acceleration on the barrel is constant.
We can use the following equation for this
Because Vo is zero, the equation simplify, so we have.
Searching for the accelaration we obtain
Changing values
This is the acceleration needed to reach the velocity at the end of the barrel.
