Question

A girl of mass 50 kg jumps out of a rowing boat of
mass 300 kg on to the bank, with a horizontal velocity
of 3 m/s. With what velocity does the boat begin to
move backwards ?


plz SOLVE the question and tell the meaning of horizontal velocity​

Answer 1

Answer:

pls mark as brainliest and follow me

Explanation:

Horizontal velocity is the velocity of a body in the Horizontal direction

Answer 2

Answer:

Given:-

Mass (M1) = 50kg

Velocity (V1) = 3m/s

Mass (M2) = 300kg

Velocity (V2) = ?

By applying,

Law of conservation of momentum,

M1U1 + M2U2 = M1V1 + M2V2

50×3 + 300×0 = 50×0 + 300×V2

150 + 0 = 300V2

150 = 300V2

V2 = 150/300

= 0.5m/s.
