A 75 kg ball carrier is running to the right at 6.5 m/s. An 80 kg defender is chasing the ball carrier running at 7.0 m/s. The defender catches the ball carrier in a completely inelastic collision. What is the final speed of the defender/ball carrier mass

 6.758V

Explanation:

The computation of the final speed of the defender/ball carrier mass is shown below:-

Data provided in the question

Measurement of ball = 75 kg

Right m/s = 6.5 m/s

Defender = 80 kg

Carrying running 7.0 m/s

Based on the above information, the final speed of the defender or ball carrier mass is

As we know that

Conservation of momentum is

= Ball in Kg × Right m/s + Defender in Kg × running m/s

= 75 × 6.5 + 80 × 7

= (75 + 80)V

Therefore, the Final speed = 6.758V

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
