The height above the ground of a drone is given by h = 3.50 t, where h is in meters and is in seconds. Calculate at t=2.50 s (a) the height of the drone above the ground and (b) the velocity of the drone. At this time (t=2.50 s) the drone releases a package (c) how long does it take the package to reach the ground? Include a complete diagram of the situation.
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.

![**Problem: Calculating Drone Height and Package Drop Time**
The height above the ground of a drone is given by the equation \( h = 3.50 \, t^3 \), where \( h \) is in meters and \( t \) is in seconds.
**Tasks:**
1. Calculate at \( t = 2.50 \, \text{s} \):
- (a) The height of the drone above the ground.
- (b) The velocity of the drone.
2. At this time (\( t = 2.50 \, \text{s} \)), the drone releases a package:
- (c) Determine how long it takes for the package to reach the ground.
**Instructions:**
- Include a detailed diagram illustrating the situation.
**Solutions:**
- **(a) Height Calculation:**
To find the height \( h \) at \( t = 2.50 \, \text{s} \), substitute \( t = 2.50 \) into the height equation:
\( h = 3.50 \times (2.50)^3 \).
- **(b) Velocity Calculation:**
The velocity of the drone is the derivative of the height with respect to time:
\( v(t) = \frac{dh}{dt} = \frac{d}{dt}[3.50 \, t^3] \).
- **(c) Package Drop Time:**
After calculating the initial height when the package is released, use free-fall motion equations to determine the time for the package to reach the ground.
**Diagram Explanation:**
The diagram should visually represent:
- The drone at height \( h \) at time \( t = 2.50 \, \text{s} \).
- The release of the package from the drone.
- The trajectory and height change of the package until it reaches the ground.
Ensure the diagram includes all relevant labels, such as heights, times, and motion directions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F56b9ddaf-a5b9-4606-96af-f9c7010351c4%2F2b50f5ba-afec-40d5-a682-6e5b14e1717b%2Fa203wz_processed.png&w=3840&q=75)
