Answer :
Usain Bolt's average momentum during his world record 100 meter dash was 977.6 kg*m/s, calculated by multiplying his mass of 94 kg by his average speed of 10.4 m/s.
The momentum of an object is defined as the product of its mass and velocity. To find Usain Bolt's average momentum during his world record 100 meter dash of 9.58 seconds, we use the formula p = mv, where m is mass and v is average velocity. Given that Usain Bolt's mass was 94 kg and his average speed was 10.4 m/s, we can calculate his average momentum as follows:
p = mv = (94 kg)(10.4 m/s) = 977.6 kg*m/s.
Therefore, Usain Bolt's average momentum during the 100 meter dash, where he set a world record, was 977.6 kg*m/s.

What is momentum ?
momentum is the result of a particle's mass and velocity. Being a vector quantity, momentum possesses both magnitude and direction. According to Isaac Newton's second equation of motion, the force applied on a particle is equal to the time rate of change of momentum.
According to Newton's second law, if a particle is subjected to a constant force for a specific amount of time, the result of the force and time (referred to as the impulse) is equal to the change in momentum. On the other hand, a particle's momentum represents the length of time needed for a consistent force to bring it to rest.
Average velocity,
v = distance / time
= 100 m / 9.58 s
= 10.44 m/s
Now use:
momentum = m*v
= 94 Kg * 10.44 m/s
= 981.21 Kg m/s
