Falling objects experience air drag that slows down acceleration; thus a falling drop of rain will eventually reach terminal velocity and doesn't go any faster because of the drag. At this velocity the momentum of the drop is not sufficiently large to damage flowers.

Raindrops are perfect spheres of water that fall at a maximum speed of 14 mph (about 21 kph) , they will not damage petals, or flowers, due to the flexibility of the plant.
Of course, rain can be accelerarted by high wind, which, if anything, tries to corrupt the sphere of the raindrop and therefore makes it more prone to exploding on contact, hence you'll get wetter, and feel colder in a rainstorm.
Plants cope mainly by being supple enough to cope with the strong winds, and only in exceptional circumstances will the weather have an effect on the natural process that is life.

Because most flowers will flex as the raindrop hits them. As long as the raindrop isn't too heavy, the flowers will bend with the rain and "roll with the punch". In some cases, like during a thunderstorm, the rain is in fact too heavy and pushes the flower all the way down to the ground. Within a couple of days the flowers will straighten back up.

Flowers will closeup as the sun disappears this protects the delicate part of the flower. Plants in general seem to know when the rain is coming, Trees will turn thier leaves upside down and flowers "close up".

Force = Mass x Acceleration
but there is also force pushing the flower up that resists the force of the raindrop
since rain hits as individual drops that have low mass and not and the only acceration is the force of gravity (9.81 m/s^s) it has a relativily low force
the force from a hose is much stronger. It has much more acceleration than just gravity.

The same reason that rain doesn't take the skin off your face when it falls on you.

The speed of the droplets does not increase indefinitely because of friction with the air.

because they like the rain. Because water is soft on their petals.
