1. What is the magnitude of the momentum of a 28g sparrow flying with a speed of 8.4m/s?
- oubaasLv 71 month ago
Momentum P = m*V = 0.028*8.4 = 0.24 kg*m/sec

Probably best to answer in KMS system.
28g (1 kg/1000g) = 0.028 kg
P = mv
P = 0.028 kg * 8.4 m/s = 0.2352
Now round to 2 sigfigs: 0.24 kg m/s
- AshLv 71 month ago
momentum = mass * velocity
= (0.028 kg)(8.4 m/s)
= 0.2352 kg m/s
≈ 0.24 kg m/s (with 2 sig fig)
