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)
What else can I help you with?
How will the speed of a ball thrown upward and a ball thrown downward compare upon striking the ground?
The speed of a ball thrown upward upon striking the ground will be the same as the speed at which it was thrown, but in the opposite direction. The speed of a ball thrown downward upon striking the ground will be faster than the speed at which it was thrown due to the acceleration from gravity.
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?
Slower than the initial speed it was thrown upward with due to air resistance causing the ball to lose speed as it travels through the air. The force of air resistance acts against the direction of motion and slows down the ball.
What is the velocity of a ball thrown upward at 16 feetsec?
The velocity of the ball is 16 feet/sec when it is thrown upward.
Which best describes the speed of a ball as it is thrown straight up into the air and comes back down?
The speed of the ball is greatest when it is thrown upward and decreases as it reaches the peak of its trajectory. The speed continues to decrease as the ball falls back down due to the force of gravity pulling it towards the ground.
What is the velocity of a ball thrown upward at 16 ft per second?
The initial velocity of the ball thrown upward at 16 ft per second is 16 ft/s.
How will the speed of a ball thrown upward and a ball thrown downward compare upon striking the ground?
The speed of a ball thrown upward upon striking the ground will be the same as the speed at which it was thrown, but in the opposite direction. The speed of a ball thrown downward upon striking the ground will be faster than the speed at which it was thrown due to the acceleration from gravity.

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
What is the velocity of a ball thrown upward at 16 feetsec?
The velocity of the ball is 16 feet/sec when it is thrown upward.
Which best describes the speed of a ball as it is thrown straight up into the air and comes back down?
The speed of the ball is greatest when it is thrown upward and decreases as it reaches the peak of its trajectory. The speed continues to decrease as the ball falls back down due to the force of gravity pulling it towards the ground.
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 the velocity of a ball thrown upward at 16 ft per second?
The initial velocity of the ball thrown upward at 16 ft per second is 16 ft/s.
What is the velocity of a ball thrown upward at 16 ft-sec?
The velocity of a ball thrown upward at 16 ft/sec would be 16 ft/sec when it leaves the hand, but it will decrease due to gravity as it moves upward.
Why a ball thrown upward again return to the point of projection?
A ball thrown upward returns to its point of projection due to the force of gravity acting on it. Gravity continuously pulls the ball back towards the Earth, causing it to eventually reach its original point of release. This process is governed by the laws of physics related to gravity and projectile motion.
When ball is thrown upward what will be constant?
The only constant when a ball is thrown upward is the acceleration due to gravity acting in the opposite direction to the velocity of the ball. Other factors, such as air resistance and the initial velocity of the ball, may change as the ball moves.
Is a ball thrown upward consider a free falling body?
A ball thrown upward is not considered a free falling body because it initially moves against gravity. Free falling bodies accelerate downward due to gravity alone, while a ball thrown upward has an initial velocity in the opposite direction.
When a ball is throw upward how does the height reached by the ball depend on its initial speed?
The height reached by a ball thrown upward depends on its initial speed: the higher the initial speed, the higher the maximum height reached. This is because a greater initial speed gives the ball more kinetic energy, allowing it to overcome gravity and reach a higher position before gravity brings it back down.
