Motion of a dog is shown in this velocity vs time graph. A. What is the acceleration from 6 to 10 seconds?

B. What is the total average acceleration?

C. What is the displacement from 6 to 10 seconds?

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
