Question

A gust of wind blows an apple from a tree. As the apple falls, the force of gravity on the apple is 9.20 N downward, and the force of the wind on the apple is 1.16 M to the right. What is the magnitude of the net external force on the apple

Answer 1

9.27 N

Step-by-step explanation:

There are two forces acting on an apple.

F1 = 9.20 N downwards

F2 = 1.16 N rightwards

these two forces are acting at right angle to each other.

Use the formula of vectors to find the resultant of two forces

`R = \sqrt{A^(2)+B^(2)+2AB Cos\theta }`

According to the question angle is 90°.

So, Resultant of to forces is

`R = \sqrt{9.2^(2)+1.16^(2)+2* 9.2* 1.16 Cos90 }`

R = 9.27 N

Thus, the magnitude of the resultant force is 9.27 N.
