A car initially at rest accellerates in a straight line at 6 m/s2. what will be its speed after 3 seconds?

Answer»

18 m per secExplanation:we have V = U + At ; V= final-velocity U = initial-velocity A =acceleration and t is timeso as STARTING fro the rest so U is zero so ;V = 0 + 6 x 3    = 18 so the SPEED is 18 meter per SECOND   please mark as brainiest
