Answer :
Final answer:
To determine the time it would take for an object initially at rest to experience a 99.8 m/s² acceleration that results in a velocity of 489 m/s, we can use the equation v = u + at.
Explanation:
To determine the time it would take for an object initially at rest to experience a
99.8 m/s² acceleration that results in a velocity of 489 m/s, we can use the
equation:
v = u + at
where v is the final velocity, u is the initial velocity (0 in this case), a is the acceleration, and t is the time. Rearranging the equation to solve for t, we get:
t = (v - u) / a
Plugging in the given values, we have:
t = (489 m/s - 0) / 99.8 m/s²
Evaluating the expression, we find that it would take approximately 4.91 seconds for the object to reach the final velocity of 489 m/s.
