Answer:
The speed of the ball at this distance is 9.15 m/s
Explanation:
Given;
initial speed of the baseball, U = 5.0 m/s.
distance traveled along the path way, h = 3 m
final speed of the baseball at this distance, V = ?
The baseball is falling under the influence of gravity.
Acceleration due to gravity, g is positive, since the baseball is falling towards its direction.
g = 9.8 m/s²
Apply the third kinematic equation;
V² = U² + 2gh
V² = 5² + 2 x 9.8 x 3
V² = 25 + 58.8
V² = 83.8
V = √83.8
V = 9.15 m/s
Therefore, the speed of the ball at this distance is 9.15 m/s
