Answer:

0.55 s

Explanation:

From the question given above, the following data were obtained:

Height (h) = 1.5 m

Horizontal velocity (v) = 25 m/s

Time of flight (t) =?

The time of flight of the potato talks about the total time spent by the potato in the air i.e the time taken for the potato to get to the ground..

Thus, we can obtain the time of flight of the potato as illustrated below:

Height (h) = 1.5 m

Acceleration due to gravity (g) = 9.8 m/s²

Time of flight (t) =?

H = ½gt²

1.5 = ½ × 9.8 × t²

1.5 = 4.9 × t²

Divide both side by 4.9

t² = 1.5 / 4.9

Take the square root of both side

t = √(1.5 / 4.9)

t = 0.55 s

Thus, the time of flight is 0.55 s

AlekseyPX

Answer:

t = 0.93 s

Part b)

d = 3.98 m

Part c)

v_x = 4.28 m/s

v_y = -11.49 m/s

Explanation:

The two components of the velocity of the ball is given as

v_x = 4.9 cos29

v_x = 4.28 m/s

v_y = 4.9 sin29

v_y = 2.37 m/s

Part a)

now we know that the displacement in y direction is given as

\Delta y = 6.4 m

so we have

\Delta y = v_y t + \frac{1}{2}gt^2

6.4 = 2.37 t + 4.9 t^2

t = 0.93 s

Part b)

Distance of the ball in x direction of the motion is given as

d = v_x t

d = 4.28 \times 0.93

d = 3.98 m

Part c)

In x direction the velocity will remain the same always

v_x = 4.28 m/s

while in Y direction we can use kinematics

v_y = v_{oy} + at

v_y = -2.37 - 9.81(0.93)

v_y = -11.49 m/s

airplane in flight has a pressure difference between the lower and upper wing surface; this provides an upward force that balanc
Dvinal [7]

Answer:

4523.17365 Pa

Explanation:

m = Mass of plane = 77000 kg

F = Force = Weight = mg

g = Acceleration due to gravity = 9.81 m/s²

A = Total area of wings = 167 m²

The pressure difference would be

\Delta P=\dfrac{F}{A}\\\Rightarrow \Delta P=\dfrac{77000\times 9.81}{167}\\\Rightarrow \Delta P=4523.17365\ Pa

The pressure difference required to keep the plane aloft is 4523.17365 Pa
