Answer:
m = 74.44 kg
Explanation:
p = m × v
670 = m × 9
9m = 670
m = 670/9
m = 74.44 kg
Momentum of an body is defined as the product of mass and velocity.It s unit is kgm/sec.The value of mass will be 74.44 kg.
The measurement of mass in motion is called momentum. Momentum is equal to its mass multiplied by its velocity. Mathematically it is given as;
Momentum = Mass x Velocity
The given data in the problem will be
p is the momentum of runner=670 kgm/sec.
v is the velocity =9m/sec.
m is the mass =?
[tex]\rm p =mv\\\\\rm m =\frac{p}{v} \\\\\rm m =\frac{670}{9} \\\\\rm m =74.44 kg[/tex]
Hence the value of mass will be 74.44 kg.
