Answer 1

Data:

p = ?

vf = ?

vi = 0

h = 80cn

a = 10m/sec^-1

m = 10kg

SOLUTION FOR VELOCITY: 2gh = vf^2 - vi^2

lets put values in following equation,

2 (10) (80) = vf^2 - 0

(20) (80) = vf^2

1600 = vf^2

TAKING UNDEROOT BOTH SIDE

vf = _/1600

vf = 40 m/sec^-2

SOLUTION FOR MOMENTUM :

P = mv

lets put values in following equation

p = 10 × 40

p = 400 N-m

the momentum = 400 N-m
