Based on the data, the car would reach a final velocity of 0 m/s. With a mass of 1500 kg, the momentum would be -15000 kg.m/sThank you for your question. Please don't hesitate to ask in Brainly your queries.
Answer:
B. The force would be the same in both cases.
Explanation:
According to Newton's 3rd law where impulse was equated to the momentum formula.
F × t = M × V
where,
Force = F
V = velocity
Since, Impulse is force multiplied by time, whereas the time of contact is the same for both, therefore the impulse is the same in magnitude for the two trucks.
Case 1: Hitting the other car
Case 2: Hitting the brick wall
In Case 1, both the cars are identical and have same velocity whereas in the Case 2, the wall is stationary.
The case of hitting the brick wall have the same impact force as hitting the other car, because they have the same change in momentum.
Therefore, The force would be the same in both cases.
Answer:
d. This statement is false. She and the Space Station share the same orbit and will stay together unless they are pushed apart.
Explanation:
In astronomy, orbit is simply a path of an object around another object in a space. That is, orbit is a path of a body that revolves around a gravitating center of mass. Examples of an orbit is are satellite around a planet, orbit around a center of galaxy, planet around the sun, and among others.
On the other hand, space station refers to a spacecraft that can support a group of human for long time in the orbit. Another names for space stations are orbital space station and orbital station.
Therefore, an astronaut goes on a space walk outside the Space Station shares the same orbit with the space station and they will stay together unless they are pushed apart.
