Question
A rocket drifts sideways in outer space from point "a" to point "b" as shown below. The rocket is subject to no outside forces. Starting at position "b", the rocket's engine is turned on and produces a constant thrust (force on the rocket) at right angles to the line "ab". The constant thrust is maintained until the rocket reaches a point "c" in space.
Beyond position "c" the speed of the rocket is:
- Continuously increasing.
- continuously decreasing.
- increasing for a while and constant thereafter.
- constant for a while and decreasing thereafter.
Transcribed Image Text:The image above displays five diagrams labeled (A) to (E), each depicting a different path from point "b" to point "C." The diagrams illustrate a variety of motion trajectories, possibly representing different types of physical motion or processes. Here is a detailed explanation of each:
1. **Diagram (A):** The path begins at point "b" and follows a curved, ascending trajectory towards "C."
2. **Diagram (B):** The pathway starts at "b" and moves straight upward in a linear fashion towards "C."
3. **Diagram (C):** The path from "b" to "C" is a diagonal line, suggesting a constant upward motion at an angle.
4. **Diagram (D):** This path follows an upward curve similar to a parabola, starting from "b" and rising steeply towards "C."
5. **Diagram (E):** The pathway is sharply curved, also resembling a parabola, with a steep ascent from "b" to "C."
Each diagram represents a different kind of trajectory, which can be used to understand varying concepts such as projectile motion or different types of growth patterns.
Transcribed Image Text:This diagram illustrates a basic concept of rocket propulsion in space.
**Description of Elements:**
- The line with arrowheads indicates the direction and trajectory of the motion.
- Point 'a' marks the initial position, where the rocket is located.
- The central figure represents a rocket.
- Point 'b' marks the final destination or direction of travel.
- The dashed line suggests a path or typical trajectory for the rocket.
**Explanation:**
In this representation, the rocket is positioned in a linear path, indicating its movement from point 'a' to point 'b'. The arrows along the dashed line suggest the force and direction of propulsion that moves the rocket through space. This concept is fundamental to understanding motion in a vacuum, where a rocket moves by expelling gas and creating thrust in the opposite direction of desired travel.

- A ball of mass m is shot straight up into the air with an initial speed vj. (a) What is the maximum height reached by the ball (in terms of vj and g)? (b) A second ball is dropped from rest from a height, h, directly above the first ball, and is released at the same time that the first ball is shot upwards. At what height will the two balls collide? Provide an expression in terms of h, Vị, and g. (c) From what height should the second ball be dropped from so that the two balls collide when the first ball is at its maximum height?arrow_forwardStarting from rest, a child throws a ball of mass m with an initial speed v, at an angle B with the horizontal direction. The child then chases after the ball, accelerating at a constant acceleration a . If the child wants to catch the ball at the same height as it was thrown, what must be the child's acceleration a ? Express your answer in terms of some or all of the variables v, m, B and g for the gravitational constant. Express the trigonometric functions in terms of the basic sin(B), cos(B) or tan(B).

That device allows you to measure the distance an object is from the device, as well as the speed and the acceleration of that object. If we decide that the origin (h = 0) is at the sonar device, we want to know what the height change is as we slide down the incline. For an angle below the horizontal of 9.74°, we see that our object has slid a distance 0.54 m, as measured along the incline itself. - Calculate the height change and report your answer as a negative number. (This value would be useful for calculating the change in gravitational potential energy, as we will do in the lab.) h=o earrow_forward
