Explanation:
We have,
Initial speed of a softball is 3.89 m/s
Deceleration of the ball is -1.44 m/s²
Distance covered by the ball is 4.8 m
It is required to find the time that the ball take when it slides. Let t is time. Using second equation of motion :
[tex]h=ut+\dfrac{1}{2}at^2[/tex]
Putting all the values we get :
[tex]4.8=3.89t+\dfrac{1}{2}(-1.44)t^2\\\\4.8=3.89t-0.72t^2\\\\t=1.9\ s \ \text{and}\ t=3.49\ s[/tex]
