Q1

As preparation for this problem, review Conceptual Example 10. The drawing shows two planes each dropping an empty fuel tank. At the moment of release each plane has the same speed of 194 m/s, and each tank is at the same height of 3.76 km above the ground. Although the speeds are the same, the velocities are different at the instant of release, because one plane is ying at an angle of 150 above the horizontal and the other is ying at an angle of 150 below the horizontal. Find the (a) magnitude and (b) direction of the velocity with which the fuel tank hits the ground if it is from plane A. Find the (c) magnitude and (d) direction of the velocity with which the fuel tank hits the ground if it is from plane B. In each part, give the direction as a positive angle with respect to the horizontal. \"wile: Fuel tank Plane A _%1: 11:5. - Plane .9 (a) Number 333.66 Units (b) Number i 187.39 Units (C) Number 333-66 Units (d) Number i 23.0478 Units An airplane with a speed of 81.0 m/s is climbing upward at an angle of 74.6 with respect to the horizontal. When the plane's altitude is 756 m, the pilot releases a package. (a) Calculate the distance along the ground, measured from a point directly beneath the point of release, to where the package hits the earth. (b) Relative to the ground, determine the angle of the velocity vector of the package just before impact
