A body of mass m = 3.513 kg is moving along the x-axis with a speed of 5.00 ms−1. The magnitude of its momentum is recorded as
Momentum, p = m \(\times\) v
= 3.513\(\times\)5.00 = 17.565 kg m/s
= 17.6 kg m/s
Here number of significant digits in m is 4 and in v is 3, so, p must have minimum (which is 3) significant digit.
