an object slides off a roof 10 m above the ground with an initial horizontal speed of 5 m per second. the time between the object's leaving the roof and hitting the ground is 1.4s. how far does it land from the wall?
Well, isn't that a smashing question! Let's see if we can solve it with a touch of humor, shall we?
So, we have an object sliding off a roof with a horizontal speed of 5 m/s. Now, imagine if that object had feet, it would be quite the speedy little fellow! And off it goes, soaring through the air, almost like a superhero soaring into action!
Now, the object takes a dashing 1.4 seconds to hit the ground. In that time, it must have been thinking, "Oh, the suspense! I'm falling, but how far will I land from the wall?"
To figure that out, we need to calculate the horizontal distance traveled by the object. Luckily, we know its initial horizontal speed, 5 m/s, and the time it takes to reach the ground, 1.4 seconds.
Using the formula distance = speed × time, we multiply the horizontal speed (5 m/s) by the time (1.4s), giving us a dazzling answer of 7 meters.
So, my hilarious friend, the object will land approximately 7 meters away from the wall. I hope that lands well with you!
To find how far the object lands from the wall, we need to calculate the horizontal distance it travels in 1.4 seconds.
Since the initial horizontal speed is 5 m/s and the time is 1.4 seconds, we can use the formula: distance = speed × time.
Therefore, the horizontal distance is:
distance = 5 m/s × 1.4 s = 7 meters.
So, the object will land 7 meters away from the wall.
To find out how far the object lands from the wall, we need to consider the horizontal motion of the object. Since there is no horizontal force acting on the object after it leaves the roof, its horizontal velocity remains constant.
In this case, the horizontal velocity of the object is 5 m/s. The time it takes for the object to hit the ground is given as 1.4 seconds.
To find the horizontal distance traveled by the object, we can use the formula:
distance = velocity * time
Plugging in the given values, we have:
distance = 5 m/s * 1.4 s = 7 meters
Therefore, the object will land 7 meters horizontally from the wall.
