A train that has a mass of 5,000,000 kg is coasting along a train track at 4 m/s when the engineer applies the brakes. As she applies the brakes, the ground exerts a force of 100,000 N on the train, in the direction opposite to the motion of the train. Eventually the train comes to a stop. What distance does it take for the train to stop?

The car would move to the right with 150 n of force. the 150 n of force from friction and air resistance slows the car from moving to the right with 300 n of force.

Indoraptor for sure

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.
