The kinematics and Newton's second law allow to find the results for the questions about the motion of the ball are:
- The acceleration is: a = 5.4 10³ m / s²
- The force is: F = 7.84 10² N
Given parameters
- Mass of the ball m = 0.145 kg
- Ball starts speed vo = 38.2 m / s
- Setback distance x = 0.135 m
To find
- Acceleration
- The force
Kinematics studies the movement of bodies, looking for relationships between the position, speed and acceleration of bodies.
v² = v₀² - 2 ax
Wher vo es la initial veloicity, a the acceleration y x is the distance,
When the ball stops the velocity is zero.
0 = v₀² - 2ax
a = [tex]\frac{v_o^2}{2x}[/tex]
Let's calculate
a = [tex]\frac{38.2^2}{2 \ 0.135}[/tex]
a = 5.4 10³ m / s²
Newton's second law establishes a relationship between force, mass, and acceleration of the body.
F = ma
F = 0.145 5.4 10³
F = 7.84 10² N
In conclusion using kinematics and Newton's second law we can find the results for the questions about the motion of the ball are:
- The acceleration is: a = 5.4 10³ m / s²
- The force is: F = 7.84 10² N
