When a ball is thrown upward with a speed of 20 ms when does it return to your hand?

Under the influence of gravity alone, the ball spends the same amount of time rising as falling.
Constant acceleration of gravity = 9.8 meters/sec.
Time continuing to rise = 20/9.8 seconds
Time to fall back an equal distance = 20/9.8 seconds
Total time from toss to catch = (2) x (20/9.8) = 40/9.8 = 4.082 seconds (rounded)

A ball is thrown upward and caught when it comes back down In the presence of air resistance the speed with which it is caught is?
less than the speed it had when thrown upward.
When a ball is thrown upward what does the height reached by the ball depend on?
The speed/force which was imparted to it when it left the thrower's hand.
How do you answer this physics question?
A ball is thrown vertically upward with an initial speed of 20m/s. Two second later, a stone is thrown vertically (from the same initial height as the ball) with an initial speed of 24m/s. At what height above the release point will the ball and stone pass each other?
What is the acceleration of a ball at the top of its trajectory when thrown straight upward?
zero
What happened to the ball when you thrown upward?
It comes back downward! :) enjoi!

When ball is thrown upward then applied force is constant why not speed of ball is constant?
because there if speed is constant than ball never come back to earth hence speed of ball is not constant
How long will it take the ball to return to earth when it is thrown straight upward at 150' per second at the height of 5'?
OW! Not long enough!

What is tje velocity of a ball thrown upward at 16 ft/sec?
If a ball is thrown vertically upward with a velocity of 160 ft/s, then its height after t seconds is s = 160t - 16t^2. If a ball is thrown vertically upward with a velocity of 160 ft/s, then its height after t seconds is s = 160t − 16t^2.
What is the momentum at the highest point of a ball thrown vertically upwards?
The highest point is the point where the ball's velocity transitions from upward to downward. At that instant, the ball's speed, velocity, momentum, and kinetic energy are all exactly zero.
How do forces help a ball speed up?
If a ball is thrown, the force pushing the ball will convert to energy to speed up the ball.
Which remains in the air longer a ball thrown upward or a ball thrown horizontally at the same speed?
Well, the ball thrown upward is obviously in the air longer before it hits the ground.It goes up for a while, before its upward speed drops to zero and it starts falling, soit effectively begins its drop from a higher altitude than a ball that you drop fromyour hand or throw horizontally.I think what you're really wanting to ask is: Which hits the ground first ... a ball thrownhorizontally or a ball just dropped from your hand ? The answer to THAT one is: If youignore air resistance, then they both hit the ground at the same time.For that matter . . . if you ignore air resistance, then it doesn't even matter if one of themis a bowling ball and the other one is a ping pong ball or a feather. They still both hit theground at the same time !Weird, no ?
Toss a ball upward what is the change in speed each second on the way up and on the way down?
The change in speed each second is the same whether the ball is going upward or downward
