The perfect elastic Collision ball will hit the door first because the clay is heavier and will take more time
hi <3
i believe the answer would be D, as when the temperature increases the particles have more energy and can overcome the activation energy more rapidly.
hope this helps :)
Answer:
29.4m/s
Explanation:
Given parameters:
Time = 3s
Unknown:
Average velocity = ?
Solution:
To solve this problem, we use the expression below:
v = u + gt
v is the average velocity
u is the initial velocity = 0m/s
g is the acceleration due to gravity = 9.8m/s²
t is the time
So;
v = 0 + (9.8 x 3) = 29.4m/s
