Question

A 12 kg object speeds up from an initial velocity of 10 m/s north to a final velocity of 15 m/s north. Calculate the change in momentum

Answer 1

60

Step-by-step explanation:

formula for change in momentum = F =∆p/∆t

F∆t = ∆p

∆p = m(v - Vo)

∆p = 12(15-10)

=12(5)= 60

Answer 2

60m/s

Step-by-step explanation:

momentum = Mass × Velocity

Initial Momentum = 12 × 10

= 120

Final Momentum = 12×15

=180

Change in Momentum = 180 - 120

= 60m/s
