Answer:
The person will travel 24 meters.
Explanation:
Distance = Rate * TIme
Distance = d = ?
Rate = r = 6 m/s
Time = t = 4 seconds
d = r*t = (6 m/s)*(4 seconds)
d = 24 m
**Note that the units (m/s) and (s/1) cancel to leave the answer in meters, the desired unit**

The solution for this problem is:
Work it backwards: spring U = ½kx² = ½ * 4000N/m * (0.10m) ²
= 20 J
so the pre-impact of KE = 20 J = ½ * m * v² = ½ * 0.40kg * v²
v = 10 m/s → for the bullet/block.
Now conserve the momentum:
50g * u = 400g * 10m/s
u = 80 m/s is the arrow
velocity
