Q1. A plane is flying horizontally with speed 169 m/s at a height 5260 m above the ground, when a package is dropped from the plane. The acceleration of gravity is 9.80 m/s 2. Neglect air resistance, when the package hits the ground, the plane would be?
Q2. A small steel ball bearing with a mass of 11g is on a short compressed spring. When aimed vertically and suddenly released, spring sends the bearing to a height of 1.21 m. compute the horizontal distance the ball would travel if the same spring were aimed 25.0o from the horizontal.
