Ball a is thrown vertically upwards with a velocity of v0 . ball b is thrown upwards from the same point with the same velocity t seconds later.
part a
determine the elapsed time t< 2v0/g from the instant ball a is thrown to when the balls pass each other .
express your answer in terms of some or all of the variables v0, t, and the acceleration due to gravity g .

If you have a bowl with six apples and you take away four, how many do you have? anyone take a guess and post it. lol getting rid of my account might as well do it with some fun

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.
