Aplane, diving with constant speed at an angle of 42.8° with the vertical, releases a projectile at an altitude of 605 m. the projectile hits the ground 6.71 s after release. (a) what is the speed of the plane? (b) how far does the projectile travel horizontally during its flight? what were the magnitudes of the (c) horizontal and (d) vertical components of its velocity just before striking the ground? (state your answers to (c) and (d) as positive numbers.)

When a charged balloon sticks to a wall, the downward gravitational force is balanced by an upward static friction force. the normal force is provided by the electrical attraction between the charged balloon and the equal but oppositely charged polarization induced in the wall's molecules. if the mass of a balloon is 1.2 g, its coefficient of static friction with the wall is 0.71, and the average distance between the opposite charges is 0.80 mm, what minimum amount of charge must be placed on the balloon in order for it to stick to the wall? express your answer to two significant figures and include appropriate units.
