Question

A rock is thrown at a window that is located 18.0 meters away. If the initial speed of the rock is 20.0 m/s, how long does it take for the rock to reach the window?

Answer 1

The time it takes for the rock to reach the window is 0.9 seconds.

Step-by-step explanation:

To calculate the time it takes for the rock to reach the window, we can use the formula for time in projectile motion:

Time = Distance / Velocity

In this case, the distance is 18.0 meters and the velocity is 20.0 m/s.

Therefore, the time it takes for the rock to reach the window is 18.0 / 20.0 = 0.9 seconds.
