Answer:
F = 1015 N
Explanation:
Given that,
Mass of a ball, m = 0.145 kg
Initial speed, u = 20 m/s
Final speed, v = -15 m/s (as it moves in opposite direction)
The ball and bat were in contact for 5 ms
We need to find the force the bat applies to the bat. We know that,
F = ma
So, the bat will apply 1015 N force to the ball.
if the distance between the objects is doubled the force is reduced by a factor of 4
<h3>Whats is gravitational force?</h3>
Gravitational force is the force of attraction between objects in the universe.
f = G * m1 * m2 / r^2
f = gravitational force
G = gravitational constant
m1 = mass of object 1
m2 = mass of object 2
r = distance between the objects
From the formular, the gravitational force and the distance is an inverse relationship so increasing the distance by a factor results to reduction of the force by the square of the factor. hence doubling the distance which is distance mutiplied by 2 will lead to reduction of the force by 2^2 = 4
Therefore: The force decreases by a factor of 4.
hope it helps
Answer:
Balanced forces do not result in any change in motion. forces: forces applied to an object in opposite directions that are not equal in size. Unbalanced forces result in a change in motion.
