Answer:
<u><em>3.721 m/s</em></u>
This is the explanation of the ans
The hero attending a funeral is safe behavior while the hero driving fast is riskier behavior
Answer:
15m/s²
Explanation:
Given parameters:
Initial velocity = 10m/s
Final velocity = 40m/s
Time taken = 2s
Unknown:
Average acceleration = ?
Solution:
Acceleration is the rate of change of velocity with time;
Acceleration =
Acceleration =
= 15m/s²
maximum allowed value of the speed in roller coaster is given as

now from kinematics we can say

here initial speed will be

acceleration is due to gravity

now we can use this to find the height



so maximum allowed height will be 20.4 m
Because you see yourself the opposite way in a mirror. So yes your “seeing” yourself but not how everyone else sees you.
