The average velocity of the car for the whole journey is 69.57 km/h.
The given parameters:
- <em>Length of the road, L = 320 km</em>
- <em>Distance covered = 240 km at 75 km/h</em>
- <em>time spent refueling, t₂ = 0.6 hr</em>
- <em>Final velocity, = 100 km/hr</em>
The time spent by the before refueling is calculated as follows;
The time spent by the car for the remaining journey;
The total time of the journey is calculated as follows;

Answer:
THE RUBBER BALL
Explanation:
From the question we are told that
The mass of the rubber ball is
The initial speed of the rubber ball is
The final speed at which it bounces bank
The mass of the clay ball is
The initial speed of the clay ball is
The final speed of the clay ball is
Generally Impulse is mathematically represented as
where is the change in the linear momentum so
For the rubber is
=>
For the clay ball
=>
So from the above calculation the ball with the a higher magnitude of impulse is the rubber ball
