Answer :
The average momentum of Usain Bolt along the straight-line path was 981.36 kg m/s.
The momentum can be defined as the product of mass and velocity. The formula for momentum can be expressed as follows:
p = mvwhere p = momentum, m = mass, and v = velocity.
We know that the mass of Usain Bolt was 94 kg and he completed 100 meters dash in 9.58 seconds. Now, we need to calculate his velocity. We can use the formula for velocity to calculate it. The formula for velocity can be expressed as follows:
v = d/t
By substituting the given values of distance (d) and time (t) into the formula, we can calculate the velocity (v) of the object.
v = 100/9.58v ≈ 10.44 m/s
Now, we can use the formula of momentum to find the momentum of Usain Bolt along the straight-line path:
p = mv = 94 kg × 10.44 m/s = 981.36 kg m/s
Therefore, the average momentum of Usain Bolt along the straight-line path was 981.36 kg m/s.
