HELP ME PLEASE. a cow is walking at a velocity of 1 m/s and speeds up to 8 m/s in 7 seconds. calculate the acceleration of the cow. round your answer to 2 decimal places

Would like to . could you translate to english

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.

Mass and velocity are the 2 factors used to calculate kinetic energy. the equation for kinetic energy is (1/2)mv^2. hope this !
