A car traveling at 7.5 m/s accelerates 3.8 m/s2 to reach a speed of 14.0 m/s.
How long does it take for this acceleration
to occur?

1) sections 1, 2, and 10 are significant primarily because they suggest the likelihood that a) widow wycherly is actually the woman in the full-length portrait. b) dr. heidegger wants to include his guests in an experiment with the water. c) dr. heidegger plans to drink some of the water from the vase and needs witnesses. d) the guests will be asked to witness dr. heidegger's transformation when he drinks the water.

Which quantities are scalars? choose all that apply a.distance b.speed c. acceleration d.velocity

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude
