Answer:
His final velocity is 15.8 m/s.
Step-by-step explanation:
Given:
Initial velocity of the driver is, m/s
Acceleration of the driver is, m/s²
Time taken to reach final velocity is, s.
The final velocity is given using the Newton's equations of motion as:
, where,
is the final velocity.
Now, plug in the given values and solve for .
Therefore, his final velocity is 15.8 m/s.
The momentum p of a moving particle is the product between its mass, m, and tis velocity, v:
In our problem, we know
and 
, and using the relationship mentioned above, we can find the mass m of the particle:
In our problem, we know
