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

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
