Answer:
d = 19.796m
Explanation:
Since the ball is in the air for 4.02 seconds, the ball should reach the maximum point from the ground in half the total time, therefore, t=2.01s to reach maximum height. At the maximum height, the velocity in the y-direction is 0.
So we know t=2.01, vi=0, g=a=9.8m/s and we are solving for d.
Next, you look for a kinematic equation that has these parameters and the one you should choose is:
Now by substituting values in, we get
d = 19.796m
So, the average speed of the Cheetah is 17.6 m/s.
<h3>Introduction</h3>Hello ! I'm Deva from Brainly Indonesia. This time, I will help regarding the average speed. The average speed is obtained from finding the average of the speeds that occur or can be detected from the division between distance and travel time. The average speed can be formulated by :
With the following condition :
= average speed (m/s)
- s = shift or distance objects from initial movement (m)
- t = interval of the time (s)
We know that :
- s = shift = 88 m
- t = interval of the time = 5 seconds
What was asked :
Step by step :
So, the average speed of the Cheetah is 17.6 m/s.
