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:
As Per Given Information
20x objective lens was used by specimen
10x ocular lens was also used by him.
we have to find the total magnification.
For calculating the total magnification we 'll simply do multiplication
Total Magnification = 20x × 10x
Total Magnification = 200x
So , the total magnification will be 200x .
Answer: 3.21 N
For weight, we will multiply by 
Hence, the rock would weigh 3.21 N.
