Question

An object of mass 200 kg is accelerated uniformly from a velocity of 10 m/s to 18 m/s in 12 s . Calculate the initial and final momentum of the object. Also, find the magnitude of the force exerted on the object. ​

Answer 1

Answer:

Helps us make more prudent decisions. Perhaps one of the most fundamental and important functions of prospection is that it helps us decide how to act: Thinking about what the future likely holds helps us decide what course to take in the here-and-now.

Answer 2

Explanation:

Momentum (P) = Mass × velocity

P(initial) = 200 × 10 =2000kgm/s

P(final) = 200 × 18 = 3600kgm/s

|F| = ∆P/∆t

RATE OF CHANGE OF MOMENTUM WITH RESPECT TO TIME

|F| = (3600 - 2000)/12

|F| = 1600/12 = 133.33Newton
