Most Upvoted Answer
From a tower of height 100m,a ball is thrown horizontally with a speed...
Solution:
Given,
Initial velocity, u = 10 m/s (horizontal)
Height of the tower, h = 100m
Acceleration due to gravity, g = 9.8 m/s² (downwards)
We need to find the time taken by the ball to reach the ground.
Approach:
The ball follows a projectile motion i.e. a combination of horizontal motion with constant velocity and vertical motion with constant acceleration due to gravity. We can use the equations of motion to find the time taken by the ball to reach the ground.
Calculation:
Using the equation of motion,
h = ut + 1/2 gt²
where,
h = height of the tower = 100m
u = initial velocity in the horizontal direction = 10 m/s
g = acceleration due to gravity = 9.8 m/s²
t = time taken by the ball to reach the ground
On substituting the values, we get
100 = 10t + 1/2 * 9.8 * t²
Simplifying the equation,
4.9t² + 10t - 100 = 0
On solving this quadratic equation, we get
t = 4.04s (approx)
Therefore, the time taken by the ball to reach the ground is approximately 4.04 seconds.
