Question

an object with mass m kg with speed of v m/s strikes a wall and rebounds with same angle and speed. find the magnitude of change in momentum ​

Answer 1

Hey in momentum change qstion never forget to write the initial and final velocities with sign otherwise ur answer ll nevr cm.

Answer 2

Answer:

Hey here is the answer mate

Given Mass = M kg

as mass is in kg so now same the unit = 1/1000g

Velocity = m/s

So now they are saying the object renounced with same angle and speed so now the magnitude = (1/1000 × velocity or m/s)^2

It means 2 ( Mass × Velocity)
