Final answer:
To calculate Mr. Loza's required launch velocity to cover 250 meters, one would need to use the principles of projectile motion and divide the motion into horizontal and vertical components. However, without the height of the Yurlang Tsangpo Canyon, the calculation cannot be completed.
Step-by-step explanation:
To determine Mr. Loza's required velocity to launch his van off the Yurlang Tsangpo Canyon and land on an inflatable cushion 250 meters away, we will use the physics concept of projectile motion. We are ignoring air resistance and considering the acceleration of gravity given as 3.7 m/s2. The key to solving this problem is to understand that the motion can be divided into horizontal and vertical components.
For the horizontal motion, the velocity remains constant as there is no acceleration in the horizontal direction (ignoring air resistance). Therefore, the van must travel 250 meters horizontally while it falls vertically. Using the formula distance = velocity x time, and knowing that the time to fall vertically can be calculated using the formula time = sqrt(2*height/gravity), we can find the required horizontal velocity.
However, since the height of the canyon is not provided, and is essential to determine the time of fall, we cannot calculate the exact horizontal velocity without this information. In a hypothetical scenario where we had the height of the canyon, we would calculate the time it takes for the van to reach the ground under the influence of gravity and then use that time to calculate the necessary horizontal velocity so that Mr. Loza can successfully cover the 250 meters.
