Question

the speed of a car beginning 1500 kg increase form 36 km per hour to 72 km per hour uniformlywhat what will beh the change in momentum of the car​

Answer 1

Answer:

Mass of car: 1500kg

Velocity v

1

=36km/hr=10m/s

Momentum p

1

=1500×10=15000kg.m/s

Velocity v

2

=72km/hr=20m/s

Momentump

2

=1500×20=30000kg.m/s

Change in momentum =p

2

−p

1

=30000−15000=15000kg.m/s
