Answer 1

Answer:

$option \: (a)15000kg \: \frac{m}{s}$

Explanation:

The change in momentum of a car weighing 1500 kg when its speed increases from 36 km/h to 72 km/h = =30000 kg.m/s − 15000 kg.m/s = 15000 kg.m/s.

Answer 2

Answer:

Final Momentum = 1500 × 20 kg.m/s = 30000 kg.m/s. The change in momentum of a car weighing 1500 kg when its speed increases from 36 km/h to 72 km/h = 30000 kg.m/s − 15000 kg.m/s = 15000 kg.m/s.
