ok will help please follow me ☺️

Explanation:

Mass of Car (m) = 2000 kg.

Initial velocity of car =36km/h=

60×60

36×1000

=10m/s

Final velocity of the car, v=0km/h=0m/s

time taken = 10 s.

Change in momentum rating place in 1s is called rate of change of momentum.

So, rate of change of momentum =

Time taken

Total change in momentum

=

Time taken

Final momentum - initial momentum

Rate of change of momentum =

t

mv−mu

=

t

m(v−u)

Change in momentum in 1s =

10

2000×(0−10m/s)

=

10

2000×(−10)

kgm/s

2

=−2000N

Negative sign indicates that momentum is decreasing.

So, momentum decreases by 2000 N in 1s

Answer:

p = mv

p = 2000 \times 36 \times  \frac{5}{18}

p =  \frac{2000 \times 36 \times 5}{18}

p = 20000kgm \: per \: sec
