Answer:
24.2 s
29.2 m
Explanation:
First, convert each speed from km/h to m/s.
91.5 km/h = 25.42 m/s
77.5 km/h = 21.53 m/s
The speed of the cheetah relative to the gazelle is:
v = 25.42 m/s − 21.53 m/s
v = 3.89 m/s
So the time it takes for the cheetah to catch the gazelle is:
x = v t
94.2 m = (3.89 m/s) t
t = 24.2 s
If instead we want to find x so that t = 7.5 s, then:
x = v t
x = (3.89 m/s) (7.5 s)
x = 29.2 m

Answer:
A vibration or oscillation is a periodically repeated reversal of the direction of movement.
Explanation:
Une vibration ou une oscillation est une inversion répétée périodiquement de la direction du mouvement.
Here is just another definition.
A vibration is periodic back-and-forth motion centerd around it's equilibrium.
