Question

please help me fast. ​

Answer 1

Answer:

Given

m=1600 kg

u=30m/s

v=0

t=20s

Now

Initial momentum is

= p=m*u

= 1,600kg * 30m/s

= 54,000 kg m/s

Now

Final momentum is

= p=m*v

= 1,600kg *0 m/s

= 0 kg m/s

Answer 2

Answer:

a. 54000 kg m/s

b. 0 kg m/s

Explanation:

given, m = 1600 kg

u = 30 m/s

v = 0

t = 20 sec.

now, initial momentum = p=m*u

=1600 kg m/s*30m/s

=54000 kg m/s

final momentum = p=m*v

=1600 kg m/s*0m/s

=0 kg m/s
