The Galaxy takes approximately a week to cross in hyperspace. Being a spiral galaxy, it's probably around 100,000 light years across, like ours is (Andromeda is ~120,000). Hyperspace travel is thus around 0.16 lightyears per second, or 595 light years per hour. The Raddus is probably 2-3 km long had I to guess, so approximately twice an Imperial star destroyer. Star destroyers weigh somewhere in the neighborhood of 25-50 MILLION tons. If force is mass times acceleration, and impact force is mass times instant deceleration, that's an impact force of roughly... 70-100,000,000,000,000,000,000,000,000 N/m^2, or SEVENTY TO ONE HUNDRED OCTILLION NEWTONS PER METER SQUARED. The TL;DR is that the entire first order fleet should have been obliterated instantly in essentially a supernova. And honestly that should have been the end of the film, Holdo sacrificing herself and taking down the First order fleet with her, allowing the transports to get away. Roll credits.
