Question

The mass of a goods lorry is 3500 Kg and the mass of goods loaded on it is 1500 Kg. If the Lowry is moving with a velocity 10 m/s. What will be its momentum? (1) 25000 Kg m/s 0 (2) 30000 Kg m/s (3) 40000 Kg m/s 0 (4) 50000 kg m/s​

Answer 1

Answer:

p = mv ( p = 3500 + 1500 * 10 m/s = 50000 kg m/s ans 4

Explanation:

Answer 2

Total mass=1500kg+3500kg

                 =5000kg

Velocity=10m/s

∵Momentum=Mass*Velocity

∴Momentum=(5000*10) k.gm/s

                    =50000 k.gm/s

ANSWER> (4) 50000 kg.m/s
