Answer :
Final answer:
The ball's velocity after 2.50 seconds is 10 m/s.
Explanation:
The ball's velocity after 2.50 seconds can be determined using the equation:
final velocity = initial velocity + (acceleration x time)
Since the ball is thrown straight up, its initial velocity is 35.8 meters per second and the acceleration due to gravity is -9.8 meters per second squared. Plugging in the values, we get:
final velocity = 35.8 m/s + (-9.8 m/s² x 2.50 s) = 10 m/s
