Respuesta :
The displacement is 4.0 m in downward dive
Solving :
The velocity of a diver just before hitting the water is -10.1 m/s ( i.e final velocity [tex]v_{f} = - 10.1 m/s[/tex] ).
Therefore velocity of diver before 1.20 s,
[tex]v_{i} = v_{f} + gt\\\\[/tex]
= -10.1 m/s + 9.8 m/s²(1.20)
= - 0.36 m/s
Now the displacement during the last 1.20 s of the dive, from the vertical motion,
s = [tex]v_{i} t + \frac{1}{2 } gt^{2}[/tex]
s = - 4.0 m
Thus, the displacement is 4.0 m in downward.
Definition of displacement :
the act or process of displacing : the state of being displaced a storm that caused the displacement of thousands of individuals . 2 a physics : the quantity or weight of a fluid (such as water) displaced (see displace sense 2 a) by a floating body (such as a ship) of equal weight.
What is an example of a displacement?
For example, a 4-year-old child is probably going to simply yell at a parent when they are upset. On the opposite hand, a 14-year-old might displace their frustration with a parent by fighting with a younger sibling
