Final answer:
The ball thrown forward at a speed of 12 m/s will travel 60 meters horizontally if it stays in the air for 5 seconds. This is calculated by multiplying the horizontal velocity by the time in the air.
Step-by-step explanation:
If a ball is thrown forward at a speed of 12 m/s and stays in the air for 5 seconds, the distance it travels horizontally can be found by using the formula for displacement: displacement = velocity × time. Since we're ignoring air resistance and the ball is thrown horizontally, there is no acceleration in the horizontal direction to consider. We simply multiply the horizontal velocity by the time the ball is in the air.
So, the distance traveled horizontally is:
distance = 12 m/s × 5 s = 60 meters.
The ball will travel 60 meters horizontally before it lands.
