Answer:
The block will be slide 0.36 m on the ice.
Explanation:
Given that,
Mass of arrow m₁= 80 g
Velocity of arrow u₁= 80 m/s
Mass of block m₂= 8.0 kg
Force F = 7.1 N
Using conservation of momentum




The work done is equal to the change in kinetic energy




We know that,
The work is defined as,




Hence, The block will be slide 0.36 m on the ice.
