Suppose a rocket ship in deep space moves with constant acceleration equal to 9.8 m/s2, which gives the illusion of normal gravity during the flight. (a) If it starts from rest, how long will it take to acquire a speed one-tenth that of light, which travels at 3.0 × 108 m/s? (b) How far will it travel in so doing?

Answers

Answer 1

Answer: (a).
It starts from rest, and its speed increases by 9.8 m/s every second.
One tenth the speed of light is (1/10) (3 x 10⁸ m/s) = 3 x 10⁷ m/s .
To reach that speed takes (3 x 10⁷ m/s) / (9.8 m/s²) = 3,061,224 seconds .
That's about 35 days and 10 hours.

(b).
Distance traveled = (average speed) x (time of travel)
Average speed = (1/2) of (1/10 the speed of light) = 1.5 x 10⁷ m/s .
Time of travel is the answer to part (a) above.
Distance traveled = (1.5 x 10⁷ m/s) x (3,061,224 sec) = 4.59 x 10¹³ meters
That's 45.9 billion kilometers.
That's 28.5 billion miles.
That's about 6.2 times the farthest distance that Pluto ever gets from the Sun.

The vector quantity that defines the distance and direction between two positions. It is a change in your position.

Answers

The displacement is the vector quantity that defines the distance and direction between two positions. It is a change in your position.

What is displacement?

A displacement is a vector in geometry and mechanics that has a length equal to the shortest distance between a point P's initial and final positions.

It calculates the length and angle of the net motion, or total motion, in a straight line from the starting point to the destination of the point trajectory. The translation that links the starting point and the ending point can be used to spot a displacement.

The average velocity, which is a vector for motion over a certain amount of time, is determined by dividing the displacement by the duration of the time interval.

Hence, the displacement is the vector quantity that defines the distance and direction between two positions. It is a change in your position.

I believe you're talking about displacement. It's a directional vector that depicts the movement of a point between two instances.

Explain how inertia and the shape of a loop counteract the force of gravity to keep riders from falling out when a roller coaster goes through a loop traveling upside down

Answers

When a roller coaster car goes through a loop, inertia keeps it from being pulled down by gravity. Inertia is the tendency of an object to resist a change in its motion, meaning that an object (the roller coaster car) which is already moving will resist forces that try to stop it. It will continue to try to move in a constant speed in a constant direction, even if other forces are slowing it down. The shape of the loop in a roller coaster is made so that the car can travel up it without losing its momentum. This is why a roller coaster car needs to be travelling at high speeds to go through a loop. If it weren't travelling quickly enough, the forces of gravity would pull it down before it could make it all the way through the loop.
