how much kick do solid rocket boosters on the Atlas V provide

The 5 solid boosters strapped to the Atlas V carying Juno into orbit really make that vehicle “jump off the pad” as a ULA representative so accurately put it last week prior to Juno’s launch.

Paulo Ordoveza, who attended the launch with me had the great idea of comparing launch videos of an Atlas-501 (with no boosters) with the Atlas-551 (with 5 boosters).  The above image is snapped at about T+0:05 from that comparison.  The 501 is a few meters above the pad while the 551 has cleared the tower and lightning protection system.
