Answer:
V = 1.41 m /s
Explanation:
Movement in both wood board and boy is created by internal forces . No horizontal external force acts on them . So conservation of momentum will apply on both of them for movement in horizontal direction.
Mass of wood board x velocity = mass of boy x velocity
58.1 x V = 48.3 x 1.69
V = 1.41 m /s
The correct answer is false
Explanation:
