Ahovering mosquito is hit by a raindrop that is 50 times as massive and falling at 8.1 m/s , a typical raindrop speed. how fast is the raindrop, with the attached mosquito, falling immediately afterward if the collision is perfectly inelastic?

here we will use the momentum conservation

initial total momentum = final total momentum

now plug in all data here

so the final speed will be 7.94 m/s

this could be newton#'s law of cooling. the cooling curve is exponential

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
