Plz help me Practice finding the net force of the following situations. a)
b)
TFnorm=3N
- 3 N
Ffriet=5N
Form
app = 5 N
Ffriet-5N
"gray 3 N
Foray = 3N
Net force:
Net force:
d)
norm- 20 N
Faire 40 N
1***
Foray - 20 N
Foray - 25 N
Net force:
Net force

the answer would be c

in physics zero. in muscle fatigue could be high

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
