When a ball is thrown straight up by how much does the speed decrease each second neglect air resistance?

Ignoring Air Resistance, on earth near the earths surface gravity applies a force on all bodies.
The acceleration the ball will experience is -9.8 meters per second per second (i.e. it will slow the ball down. When the ball then falls to the ground from the apogee of the throw it will continue to accelerate at 9.8 meters per second per second per second and will hit the ground at the same speed it left the ground originally.
So each second it will slow by 9.8 meters per second.
9.8 meters per second, (or 32.2 feet per second), if the experiment is carried out on or near the surface of the earth.
1.6 meters (5.25 feet) per second, if it's on or near the surface of the moon.
3.52 meters (11.5 feet) per second, if it's on or near the surface of Mars.

Which force on an airplane can also be called a resistance force?
Gravity is the main resistance force on any aircraft. Wind resistance would be second.
What is the speed of a 380 acp bullet falling straight down?
Falling, and not tumbling end over end, the bullet will accelerate (due to gravity) at 32 ft per second- per second- until it reaches the terminal velocity- limited by air resistance- around 300 mph. If tumbling end over end, more air resistance, less speed- about 225 mps MAXIMUM.
Why is tiptoe a second class lever?
Because a second class lever is a lever in which the resistance is located between the fulcrum and the effort. When you stand on your tiptoes, the fulcrum is located at your toes, the effort is at your Achilles tendon, and the resistance is the weight of your body pushing down. therefore, the resistance is between the fulcrum and the effort.
Which one of the following does not affect the electrical resistance of a body?
the second one has no affect.
The second postulate of kinetic theory states that particles move in random straight lines at various velocities and in all directions Predict the effect of decreasing the temperature of the system o?
Decreasing the temperature of the system will decrease the average velocities of the particles, but will not change their pattern of movement.
Prove Hall's theorem from Tutte' theorem graph theory?
in this theorem we will neglect the given resistance and in next step mean as second step we will solve
If the larger fish has a mass of 5 kg and swims 1 meter per second toward a 1 kg fish what is the velocity of the larger fish immediately after lunch you will neglect the effects of water resistance?
Yes.
A ball is thrown straight up from the edge of the roof of a buildinga second ball is dropped from 1sec later ignore air resistance?
... and what is the question? The second ball should arrive at the floor a second after the first, both should have the same speed.
A baseball is hit straight up at an initial velocity of 100 meters per second. What will be the baseball's speed when it hits the ground?
I assume you hit it up from the ground level as well. From Conservation of Energy, it immediately follows that: * If there is no air resistance, when it hits the ground it will, once again, have a speed of 100 meters per second. * Since under usual circumstances there WILL BE air resistance, its speed will be less than 100 meters per second.
What happens to the distance you fall during each second?
If you fall from a very considerable height then initially the distance that you fall will increase with each second that you fall. However, air resistance increases markedly with speed and this causes your acceleration to decrease so that you reach a maximum speed (terminal velocity)
Which force on an airplane can also be called a resistance force?
Gravity is the main resistance force on any aircraft. Wind resistance would be second.
What happens in a series circuit if the resistance is halved?
If you add a second resistor, the resistance of series circuit will increase.
