Understanding the Problem

In this problem, we are given the initial velocity of an object, the time it takes to reach a certain height, and the distance it travels horizontally. We need to determine the height of the table. This problem involves the application of kinematic equations in physics, specifically the equations of motion under constant acceleration.

Given Values

Initial time (t) = 0.70 m
Initial velocity (vi) = 1.50 m/s
Time (t) = 0.47 s
Horizontal distance (dx) = 0.20 m
Acceleration due to gravity (ag) = 9.8 m/s²

Calculating the Height

To calculate the height of the table, we need to use the equation of motion under constant acceleration:

dy = vi × t + (1/2) × ag × t²

where dy is the height of the table, vi is the initial velocity, t is the time, and ag is the acceleration due to gravity.

Step 1: Calculate the Height

First, we need to calculate the height of the table using the given values:

dy = vi × t + (1/2) × ag × t² = 1.50 m/s × 0.47 s + (1/2) × 9.8 m/s² × (0.47 s)² = 0.705 m + 1.065 m = 1.77 m

Step 2: Calculate the Horizontal Distance

Next, we need to calculate the horizontal distance traveled by the object:

dx = vi × t = 1.50 m/s × 0.47 s = 0.705 m

Step 3: Calculate the Vertical Distance

Now, we need to calculate the vertical distance traveled by the object:

dy = (1/2) × ag × t² = (1/2) × 9.8 m/s² × (0.47 s)² = 1.065 m

Conclusion

In this problem, we used the kinematic equations to calculate the height of the table. We first calculated the height using the equation of motion under constant acceleration, and then calculated the horizontal distance and vertical distance traveled by the object. The final answer is:

The height of the table is 1.77 m.
