This question can be solved by using Pythagora's Theorem.
The resultant magnitude of the movement is "42.5 units".
The x and y components of the movement are given. We can use Pythagora's Theorem to find the resultant of these movements. Hence, applying the Pythagora's Theorem<em>:</em>
where,
d = resultant movement = ?
= movement in x direction = 32 units
= movement in y direction = 28 units
Therefore,
<u>d = 42.5 units</u>

B. The resistance is directly proportional to length and inversely proportional to cross sectional area
Answer:
S = 11.025 m
Explanation:
Given,
The time taken by the pebble to hit the water surface is, t = 1.5 s
Acceleration due to gravity, g = 9.8 m/s²
Using the II equations of motion
S = ut + 1/2 gt²
Here u is the initial velocity of the pebble. Since it is free-fall, the initial velocity
u = 0
Therefore, the equation becomes
S = 1/2 gt²
Substituting the given values in the above equation
S = 0.5 x 9.8 x 1.5²
= 11.025 m
Hence, the distance from the edge of the well to the water's surface is, S = 11.025 m
