Question

A food packet is dropped from a plane flying horizontally.
a)sketch the path of the falling food packet.
b)if the time taken by the packet to reach the earth '6'seconds, calculate the height from which the packet is dropped. (take g =10m/s)

Answer 1

Answer:

a) parabola

Explanation:

b) displacement is 5* 36 = 180m.

Answer 2

The height from which the food packet falls is 180 meters

Given:

Time taken is 6 seconds

Earth's gravity is taken as 10m/s

To Find:

The height from which the food packet falls should be calculated

Solution:

T = 6 seconds

$U_{y}$ = 0  and  $a_{y}$ = 0

Consider, the equation

$S_{y} = U_{y} t +\frac{1}{2} a_{y} t^{2}$

The height can be calculated from the above equation,

$S_{y}$ =  $\frac{1}{2} (10)(6)(6)$

    = 180 meters

Hence, the height from which the food packet is dropped is

180 meters.
