Question

iii) If another ball of mass 20 g is struck by a bat and its velocity is 10 ms, then (1 Point)

(a) the change in momentum of the ball will be -0.2 kg-m/s
(b) the change in momentum of the ball will be 0.2 kg-m/s
(c) the change in momentum of the ball will be 0.8 kg-m/s
(d) the change in momentum of the ball will be 0.8 kg-m/s 23​

Answer 1

Answer:

P=MV

m=20g

v=10 M/s

P=20×10

p=200g-m/s

1KG=1000g

so,0.2kg-m/s
