A car is traveling at a constant speed when the driver applies the brakes, giving the car a deceleration of 4.20 m/s^2. If the car comes to rest in a distance of 25.0 m, what was the car’s original speed?

An object is thrown straight upward with a speed of 19.6 m/s. How long does it take to reach maximum height?

The ……………………………………. is a dedicated HDFS implementation used in HDFS HA to provide a highly available shared edit log. It is the recommended choice for most HDFS installations.

The mappers and reducers write their output to HDFS.

Consider the sample CapacityScheduler configuration file given below, which creates and configures two queues, namely: XYZ and ABC. yarn.scheduler.capacity.root.queues XYZ, ABC yarn.scheduler.capacity.root.XYZ.capacity 60 yarn.scheduler.capacity.root.ABC.capacity 40 yarn.scheduler.capacity.root.XYZ.maximum-capacity 80 1. How much of the cluster resources will be used by a job running in queue ABC, assuming that it is the only job in the cluster? Answer in percentage: _______ %  2. How much of the cluster resources will be used by a job running in queue XYZ, assuming that it is the only job in the cluster? Answer in percentage: _______ % 3. How much of the cluster resources will be used by jobs in queue ABC, assuming that there are many jobs running in ABC and queue XYZ is idle? Answer in percentage: _______ %  4. How much of the cluster resources will be used by jobs in queue XYZ, assuming that there are many jobs running in XYZ and queue ABC is idle? Answer in percentage: _______ %
