A small ball is thrown horizontally from a height of with an initial speed of . Neglecting air resistance and taking , what is the time taken for the ball to reach the ground?
Options
A
2 s
B
1 s
C
0.5 s
D
1.5 s
Answer & Analysis
Answer
B
Analysis
To find the time taken for the ball to
reach the ground, we can use the vertical motion equation for free fall.
Height (h): 5 m
Acceleration due to gravity (g):
Using the equation of motion:
We can rearrange this to solve for time
(t):
