Explanation:
It is given that,
Speed of the baseball, u = 44 m/s
Speed of the baseball, v = 53 m/s
Mass of the ball, m = 145 g = 0.145 kg
Time of contact between the ball and the bat, t = 2.2 ms = 0.0022 s
F₁ = 2900 N...........(1)
F₂ = 3493.18 N.........(2)
In average vector form force is given by :
Hence, this is the required solution.
Answer: The answer is B
Explanation: A correlation generally is a mutual relationship/connection or the process of establishing the relationship/connection between 2+ things
The one that would explain why the two groups of scientists got different results is :
They had different specialties and interpreted their data differently
Probably one analyze it with x theory and the other use y theory
hope this helps
You can calculate potential energy by:
U = m.g.h
Where, U = potential energy
m = mass
g = acceleration due to gravity
h = height
Hope this helps!
