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: 0.5 m
Explanation:
Given
Mass of the person is
Trampoline launches the person into the air up to height of
Force experience by springs is
Here, the work done on displacing the springs is equivalent to the Potential energy acquired by the person i.e.
