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 when the ball is tossed upward will decrease by 9.8 m/s each second due to gravity until it reaches its highest point and starts falling back down. On the way down, the speed will increase by 9.8 m/s each second as gravity accelerates the ball towards the ground.
Can an object be accelerating when it speed is zero?
Yes. There can be an instant during a period of acceleration when speed is zero. We can think of two examples right away: 1). Drop an object from your hand. As soon as you release it, downward acceleration begins immediately, but speed is zero. 2). Toss an object (like a baseball or a stone) straight up. Downward acceleration due to gravity begins immediately. At first, its effect is to reduce the upward speed. As soon as the upward speed is all gone, downward speed begins. Acceleration is constant throughout, but at the instant when upward speed becomes downward speed, the speed is zero.
Is it possible for an object with constant negative acceleration to change the direction in which it is moving?
Sure. Anything you toss with your hand has constant acceleration after you toss it ... the acceleration of gravity, directed downward. If you toss it upward, it starts out with upward velocity, which reverses and eventually becomes downward velocity.
What speed must you toss a ball straight up so that it takes 4 s to return to you?
To toss a ball straight up so that it takes 4.0 seconds to return to you, it must be thrown at a speed of 19.6 meters per second. This is because it will have a speed of zero at 2.0 seconds, therefore it must have a speed of 19.6 meters per second for gravity's 9.8 meters per second squared to slow it to zero in 2 seconds.
What is the energy transformation that occurs when you toss a fall upward and it falls?
When you toss a ball upward, the initial energy transformation is from mechanical energy (kinetic energy) to potential energy as the ball gains height. As the ball falls back down, the potential energy is converted back into kinetic energy as it accelerates towards the ground.

How is it that A ball is projected straight up from the ground with a speed of 7.61 meters per second To what maximum height will the ball go when gravity equals 9.80 meters per second squared?
Initial upward speed = 7.61 m/sFinal upward speed (at the point of maximum height) = 0Time to reach maximum height = (7.61) / (9.8) = 0.77653 secondAverage speed during that time = 1/2 ( 7.61 + 0) = 3.805 m/sHeight = 3.805 x 0.77653 = 2.9547 meters (rounded) = about 9.7 feetDoesn't seem like much of a height for a strong toss; but the math looks OK.
What is the probability of getting tails on the first toss and heads on the second toss?
1 in 2 to get tails on first toss 1 in 2 to get heads on second toss To get tails on first toss and heads on second toss, probability is 1/2 x 1/2 = 1 in 4

When you toss a ball upward, the initial energy transformation is from mechanical energy (kinetic energy) to potential energy as the ball gains height. As the ball falls back down, the potential energy is converted back into kinetic energy as it accelerates towards the ground.

Can an object with a constant acceleration reverse its direction of travel?
Of course. Anything you toss with your hand has constant acceleration after you toss it ... the acceleration of gravity, directed downward. If you toss it upward, it starts out with upward velocity, which reverses and eventually becomes downward velocity.
Describe the energy transformations that occur when you toss a ball upward and it falls?
When you toss a ball upward, your body applies kinetic energy to the ball, giving it potential energy as it rises. As the ball falls back down, its potential energy is converted back into kinetic energy, leading to a decrease in potential energy and an increase in kinetic energy until it reaches the ground.
A coin is tossed 2 times what are the number of possible outcomes?
There are 4 possible outcomes. There are 2 outcomes (heads or tails) on the first toss and 2 on the second toss. The possibilities are HH, TT, HT and TH.
What does it mean if a team accepted the toss or declined it?
There is no accept or declining of a coin toss. The team that wins can decide to receive the ball or to defer to the second half.
