Answer:
, 
Explanation:
From the question we are told that
The initial velocity of the arcade ball is 
The time taken by the ball to enter the basket is 
Generally the x -component of the initial velocity is
=>
Generally the y -component of the initial velocity is
=> 
Generally the distance x is mathematically represented as

=>
=>
Generally from kinematic equation the distance y is mathematically represented as

=> 
=> 
Answer:
equal
Explanation:
Because of Newton's third law
Answer:
A chemical change produces a new substance, while a physical change does not
Answer:
8 J and 2 J
Explanation:
Given that,
Mass of the rubber ball, m = 1 kg
Initial speed of the rubber ball, u = 4 m/s (in east)
Final speed of the rubber ball, v = -2 m/s (in west)
We need to find the kinetic energy of the ball before it hits the wall, the kinetic energy of the ball after it bounces off the wall.
Initial kinetic energy,

Final kinetic energy,

So, the initial kinetic energy is 8 J and the final kinetic energy is 2 J.
