Answer:
mass of the person walking to west is 65 kg.
Given:
Momentum = 52
Speed = 0.8
To find:
Mass of the person = ?
Formula used:
Momentum is given by,
P = m × v
Where, P = momentum
m = mass
v = speed
Solution:
Momentum is given by,
P = m × v
Where, P = momentum
m = mass
v = speed
Mass =
m =
m = 65 kg
Thus, mass of the person walking to west is 65 kg.
