A ball of mass 8 kg moving with a speed of 2m/s and rebounds with the same speed.Determine the impulse experienced by the ball.
It has to be 2 times 8*2 kg-m/s
remember the impulse changed its' direction.
bob what is the answer
+ 2 to - 2 = 4
8*4 = 32
To determine the impulse experienced by the ball, we can use the equation:
Impulse = change in momentum
The momentum of an object can be calculated by multiplying its mass by its velocity:
Momentum = mass * velocity
In this case, the ball has a mass of 8 kg and a velocity of 2 m/s.
Momentum before the rebound = 8 kg * 2 m/s = 16 kg·m/s
Since the ball rebounds and its velocity remains the same, the momentum after the rebound will also be 16 kg·m/s.
Now, let's find the change in momentum:
Change in momentum = Momentum after - Momentum before
= 16 kg·m/s - 16 kg·m/s
= 0 kg·m/s
Therefore, the impulse experienced by the ball is 0 kg·m/s.
