Question
Solve the following problems with complete solutions.
-
If 2.0 J of work is done in raising a 180 g apple, how far is it lifted?
Example is attached below. Please refer to it.

Transcribed Image Text:Wtotal = (Frotal Cos 0)d = Frotald cos 0
Еxample:
How much work is done on a vacuum cleaner pulled 3.0 meter by a force of
50.0 Newton at an angle of 30.0° above the horizontal?
Given:
F = 50.0 N
D = 3.0 m
Ø = 30.0°
W =?
Using the equation:
W = Fxd x cos Ø
W = (50.0 N) (3.0 m) (cos 30.0°)
W = 130 J
