You are approaching a stoplight moving with a velocity of +30.0 m/s. the light turns yellow, and you apply the brakes and skid to a stop. if your acceleration is -8.00 m/s2, then determine the displacement of the car during the skidding process. how long did it take for you to stop the car? (note: the direction of the velocity and the acceleration vectors are denoted by a + and a - sign.)

Two cars collide, lock bumpers and move together after the collision.this collision is known as perfectly inelastic collision.

How is it possible that phylogenies based on sequences from nuclear genomes and organellar genomes (i.e., chloroplasts and mitochondria) from the same group of species yield phylogenetic trees with different branching orders?   answer :   the genome of the endosymbiont is more closely related to members of the group in which it originally evolved, while the nuclear genome of the engulfing organism has its own evolutionary trajectory.
