Question

the speed of a car weighing 1500 increase from 10m/s to 20m/ s what will the change in momentum of car
​

Answer 1

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.

Answer 2

Answer:

Momentum is equal to product of mass into acceleration

initial velocity (u) = 10m/s

Mass(m) = 1500

Momentum = u×m= 10×1500=15000 kg m/s

Final velocity (v) = 20m/s

Mass(m) = 1500 kg

Momentum =m×v =1500×20 = 30000 kg m/s
