TOGETHER TO COMPLETE THESE TASKS?

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

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.

find the sum of the two horizontal vectors and the sum of the two vertical vectors
