a crate falls from an airplane flying horizontally at an altitude of 2,000 m. neglecting air drag, howlong will the crate take to strike the ground/ is the formula t = d/v help
First write out what you know:
u = 0 m/s
v = v
a = 9.81 m/s[sup]2[/sup]
s = 2000 m
t = t
then pick the appropriate formula:
s = ut + 0.5at[sup]2[/sup]
2000 = 4.905 * t[sup]2[/sup]
t[sup]2[/sup] = 407.7
t = 20.2 s
The air drag during a crate freefall at 2,000m altitude is calculated using the equation: drag force = 0.5 * air density * velocity^2 * drag coefficient * frontal area. The air density and drag coefficient are dependent on the air temperature and the shape of the crate, respectively. The velocity can be calculated using the equation: velocity = square root of (2 * acceleration due to gravity * altitude).
Air drag plays a crucial role in the descent of a crate in freefall at 2,000m altitude. It is the force that opposes the motion of the crate, slowing it down and causing it to reach terminal velocity. This allows for a controlled descent and prevents the crate from reaching dangerously high speeds.
Air density is a key factor in calculating air drag during a crate freefall at 2,000m altitude. As altitude increases, the air density decreases, resulting in a decrease in air drag. This is because there are fewer air molecules to collide with the crate and create resistance. Therefore, the air density must be taken into account when calculating the drag force on the crate.
The shape of the crate has a significant impact on the calculation of air drag during a freefall at 2,000m altitude. The drag coefficient, which is a measure of how streamlined an object is, is heavily dependent on the shape of the crate. A more streamlined shape will have a lower drag coefficient and experience less air resistance, resulting in a lower drag force.
In addition to air density and crate shape, other factors that should be considered when calculating air drag during a crate freefall at 2,000m altitude include wind speed and direction, air temperature, and altitude change over time. These factors can all affect the drag force acting on the crate and should be taken into account for a more accurate calculation.
