Question

A cannon is launched horizontally with an initial velocity of 23.8 m/s. it goes a horizontal range of 134 m. how long will it take the projectile to hit the ground?

Answer 1

The time it takes for the projectile to hit the ground is 0 seconds.

Step-by-step explanation:

To find the time it takes for the projectile to hit the ground, we need to consider the vertical motion. In this case, the initial vertical velocity is 0 m/s because the cannon is launched horizontally. The equation to calculate the time of flight is t = 2h/g, where h is the vertical displacement and g is the acceleration due to gravity (9.8 m/s^2). Since the cannonball lands at the same height as it was launched, h = 0. Therefore, the time of flight is 0 seconds.

answer = 0 sec
