A car starts from rest and accelerates uniformly over a time of 5.21 seconds for a distance of 110 m. Determine the acceleration of the car. Choose the appropriate equation. Options: v=v_o+at, d=v_ot+1/2at², v²=v_o²+2ad, d=1/2(v+v_o)t

Back

d=v_ot+1/2at²

Rocket-powered sleds are used to test the human response to acceleration. If a rocket-powered sled is accelerated to a speed of 444 m/s in 1.83 seconds, then what is the distance that the sled travels? Choose the appropriate equation: v=v_o+at, d=v_ot+1/2at², v²=v_o²+2ad, d=1/2(v+v_o)t

Back

d=1/2(v+v_o)t
