Answer:
Vf = 98 m/s
Step-by-step explanation:
The dime is in a free fall motion under the influence of gravity. For the final velocity of the dime, we use 1st equation of motion here:
Vf = Vi + gt
where,
Vf = Final Velocity = ?
Vi = Initial Velocity = 0 m/s (Since, the initially the dime was at rest)
g = acceleration due to gravity = 9.8 m/s²
t = time taken = 10 s
Therefore, using these values, we get:
Vf = 0 m/s + (9.8 m/s²)(10 s)
Vf = 98 m/s
