A raindrop of mass 3.22 10-5 kg falls vertically at constant speed under the influence of gravity and air resistance. Model the drop as a particle. (a) As it falls 70 m, what is the work done on the raindrop by the gravitational force

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

the answer to this is proletariats.

hope this : )
