Answer:
352kg.m/s
Explanation:
Momentum is the product of mass and velocity. Momentum is a vector quantity. Momentum is the measurement of an object in motion thereby showing how much of the object is in motion. The formula of momentum (p) is given as:
p = mass * velocity
Given that the runner has mass of 55 kg, the momentum at a speed of 6.4 m/s is:
Momentum = mass * velocity = 55 * 6.4 = 352kg.m/s
