Question

1. (a) Define momentum. Write its SI unit.
(b) How much momentum will an object of mass 10kg transfer to the floor if it falls from a height of 5 m? (g= 10m/s²)

Answer 1

Answer:

Momentum {p}

p = vector Quantity

p = mV

p = Kgm/s

b )

Vi = 0

vf = √2gh = 10m/s

∆p = m(vf -vi)

∆p = 10 × 10 = 100kgm/s

Answer 2

MOMENTUM:

THE MOMENTUM OF A BODY IS DEFINED AS THE PRODUCT OF MASS(M) AND VELOCITY(V).

P=MV

IT'S S.I UNIT IS KG METER PER SECOND.
