Accelerate Your Learning with Exciting Physics Problems!
First, we know that the initial velocity u is 19.6 m/s, the acceleration a is 9.8 m/s², and the time t is 5 seconds. Plugging these values into the equation v = u + at:
v = 19.6 m/s + (9.8 m/s² × 5 s)
v = 19.6 m/s + 49 m/s
v = 68.6 m/s
Therefore, the velocity of the freely falling ball five seconds after it has reached 19.6 m/s is 68.6 m/s. With these calculations, you can see how physics concepts and formulas can be applied to solve real-world problems.
