If you want to change kilometers in to metres you need to multiply it by 100.
You need to post a picture bro
Important is source , the race of victim , the age , the fatness of his/her body
To solve this problem we will apply the concept related to momentum, which is a physical quantity derived from a vector type that describes the movement of a body in any mechanical theory. In classical mechanics, the amount of movement is defined as the product of body mass and its velocity at a given time. Mathematically is written as,
Here,
m = Mass
V = Velocity
Our values are
Replacing,
Therefore the magnitude of the momentum of a baseball thrown at a speed of 99miles per hour
Answer: Option A
Explanation:
When she moves her hand in the same direction that the ball, the speed in which the hand "sees" the ball (or a viewer in the frame of the motion of the hand) is smaller.
This means that the difference in the kinetic energy (that is written as k = (1/2)m*v^2) between the and the ball is smaller, then the change in the kinetic energy of the hand when the ball impacts it is also smaller, then the "force" of the impact is smaller.
The correct answer would be A, the relative velocity of the ball is less, which translates into a reduction in the force of impact (or the change in the kinetic energy of the hand)
