Question

The Speed of a car weighing 1500 kg increases from 36 Km/h to 72 Km/h uniformly. What will be the change in momentum of the car? If the time is 10 Sec ,then find the acceleration also​

Answer 1

Answer:

Momentum of car at speed 36km/h=10m/s=m×10

=1500×10

=15000kg m/s

Momentom of car at speed 72km/h=20m/s=m×20

=1500×20

=30000kg m/s

Momentom change=30000−15000=15000kg m/s

Answer 2

Answer:

30000 kg

Explanation:

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.
