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.
Why does the speed dcreses when an object is thrown vertically up?
The speed decreases when an object is thrown vertically up because of the force of gravity acting against the object's upward motion. As the object goes higher, the force of gravity slows it down until the object reaches its maximum height, where its speed momentarily becomes zero before accelerating back downward.
Find speed throwing object straight up and return 6 seconds later?
To find the speed at which the object was thrown upward, we need to know the acceleration due to gravity. Assuming g ≈ 9.81 m/s², the initial speed of the object can be calculated using the equation v = u - gt, where v is the final speed (0 m/s when it returns), u is the initial speed, g is the acceleration due to gravity, and t is the time (6 seconds). This calculation will give you the initial speed at which the object was thrown upward.
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?
Can you cite an example in which the acceleration of a boby is opposite in direction to it's velocity?
When an object is thrown upward, the acceleration due to gravity acts downward while the velocity is directed upward. This leads to a decrease in the speed of the object until it reaches its highest point and changes direction.

Does two stones have the same acceleration if one is thrown upward from a roof and the identical one is dropped from there?
no because the higher it gets the speed increases and its do not does.

A stone is thrown straight upward and it rises to a height of 20 meters With what speed was it thrown?
To determine the initial speed, you can use the kinematic equation: v² = u² + 2as, where v is the final velocity (0 m/s at the top), u is the initial velocity, a is acceleration (gravitational acceleration at -9.8 m/s²), and s is the displacement (20 m). Solving for u, you get u = sqrt(2as) = sqrt(2*-9.8*20) = 19.8 m/s. So, the stone was thrown upward with a speed of 19.8 m/s.
When an object is thown upward how much speed does it loose each second?
When an object is thrown upwards, it loses 9.8 meters per second of speed due to gravity acting against its motion. This is the acceleration due to gravity on Earth, which causes the object to slow down as it moves upward.
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.
A ball is thrown vertically upward. What are its velocity and acceleration when it reaches its maximum altitude What is the acceleration of the ball just before it hits the ground?
At the maximum altitude, the ball's velocity is zero and its acceleration is equal to the acceleration due to gravity, pointing downwards. Just before hitting the ground, the acceleration of the ball is still equal to the acceleration due to gravity, pointing downwards.
Can an object have a speed of 0 while it has an acceleration that is not 0?
Yes, an object can have a speed of 0 while still having a non-zero acceleration. This can happen when the object is changing direction but not speed, such as in circular motion or in the case of an object at rest on an incline under the influence of gravity.
What is the momentum at the highest point of a ball thrown vertically upwards?
At the highest point of its trajectory, a ball thrown vertically upwards has zero velocity. Since momentum is the product of velocity and mass, the momentum of the ball at the highest point is also zero.
