Question

A body of mass 5g moves with an acceleration of 2m/s. Find the change in momentum in 2 seconds

Answer 1

Heya......!!!

________________________

Given in the question. :

=> Acceleration ( a ) = 2 m/s²

=> Mass of body ( m ) = 5g = 5/1000 kg

=> time ( t ) = 2 sec

Velocity ( Δ v ) = Acceleration*time

⇒ Δv = 4 m/s

Change in momentum ( Δp ) = m*(Δv)

⇒ Δp = 5/1000*4

Change in Momentum = 1/50 Kg m/sec

Hope It Helps You. ^_^

Given data:

=> Acceleration ( a ) = 2 m/s²

=> Mass of body ( m ) = 5g = 5/1000 kg

=> time ( t ) = 2 sec

Velocity ( Δ v ) = Acceleration*time

⇒ Δv = 4 m/s

Change in momentum ( Δp ) = m*(Δv)

⇒ Δp = 5/1000*4

Change in Momentum = 1/50 Kg m/sec
