Narrative:
On takeoff roll after 80 kts. Received a batt 1 off bus master caution after hitting a hard bump on the runway. We continued the roll out and take off. After gear up received a landing gear lever a/g fail master caution. Followed by a eng 1;2 thrust reverser disagree. The thrust lever interlocks started clicking in rapid succession and continued until landing configuration. We asked to remain in the terminal area while we ran the QRH. After running the QRH we advised ATC and setup for a extended downwind for runway 27L because there was concern we may have had degraded braking; no spoilers; and no reversers. We made a flaps 45 landing and on landing the nose strut fully compressed putting the aircraft at an unusually low nose down pitch. Upon reaching the gate maintenance informed us of a fully compressed nose wheel strut.we detected the chain of events on takeoff rollout just after reaching 80 kts.unsure of the root cause.we ran the QRH and then advised ATC and completed landing and returned to the gate without incident.
