A ball is tossed upward with an initial velocity of 25 meters / second. Assume that the acceleration of gravity is 10 m/s^2 downward.
What will be the velocity of the ball after one second?
answer/question/discussion: ->->->->->->->->->->->-> :
15 m/s
#$&*
What will be its velocity at the end of two seconds?
answer/question/discussion: ->->->->->->->->->->->-> :
5 m/s
#$&*
During the first two seconds, what therefore is its average velocity?
answer/question/discussion: ->->->->->->->->->->->-> :
15 m/s
#$&*
How far does it therefore rise in the first two seconds?
answer/question/discussion: ->->->->->->->->->->->-> :
30 m
#$&*
What will be its velocity at the end of a additional second, and at the end of one more additional second?
answer/question/discussion: ->->->->->->->->->->->-> :
-5 m/s , -15 m/s
#$&*
At what instant does the ball reach its maximum height, and how high has it risen by that instant?
answer/question/discussion: ->->->->->->->->->->->-> :
2.5 seconds , 31.25
#$&*
What is its average velocity for the first four seconds, and how high is it at the end of the fourth second?
answer/question/discussion: ->->->->->->->->->->->-> :
5 m/s , 20 , m
#$&*
How high will it be at the end of the sixth second?
answer/question/discussion: ->->->->->->->->->->->-> :
-30 m/s
