Question

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

Answer 1

Answer:

 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
