Answer:
v = 747.83 m/s
Explanation:
given,
mass of bullet, m = 10.7 g
= 0.0107 Kg
mass of the wooden plank, M = 4588 g = 4.588 Kg
speed of the block and the bullet together, V = 1.74 m/s
initial speed of the plank = 0 m/s
using conservation of momentum
m v + M u = ( M + m ) V
0.0107 x v + 0 = (4.588 + 0.0107) x 1.74
0.0107 v = 8
v = 747.83 m/s
now, speed of the bullet is equal to 747.83 m/s.
Answer:
Transfer
Explanation:
bc energy cannot be created not destroyed so instead it transforms or gets transferred.
The operator should watch you wake when operating a boat near other boats when entering a congested area because it may cause personal injury or damage. The track of waves cause a disturbed flow that may affect others near the operating boat in the area.
