In throwing a ball upward discuss the velocity and acceleration when the ball returns to the thrower's hand?

A the moment when the ball just touches the thrower's hand, it will have the velocity with which it was thrown and the acceleration will be equal to the acceleration due to gravity at the place acting vertically downwards.

Discuss if a body moving with uniform velocity is in equilibrium?
A body moving with uniform velocity is in equilibrium when it moves with uniform velocity as no acceleration i.e. no net force acts on the body.The sum of all forces must be zero in this case. (To avoid rotation, the sum of all torques must also be zero).
Discuss the motion of a body thrown from a certain height?
Ignoring air resistance, for simplicity:* The horizontal component of the velocity (if you give it an initial thrust in any direction that is not exactly down or up) will remain unchanged, until the object touches the ground. * The vertical component of the velocity will change at a rate of about -9.8 meters per second square (assuming you define positive numbers to mean upwards).
Discuss acceleration by providing at least one example and explaining why it would be considered scalar or vector?
When we ride on a motor cycle we turn the throttle and the bike's speed goes on increasing. This is positive acceleration. Now we switch off the motor. The bike comes to rest after travelling some distance. This is due to negative acceleration due to frictional force between the tyre and the floor. In this case acceleration is in opposite direction to the direction of motion of the bike. Hence acceleration becomes a vector.
Is distance the magnitude of velocity?
Remember that velocity is a vector quantity which means it needs two criteria to be defined; a magnitude, and a direction. When we discuss the magnitude of velocity, what we are talking about is the speed (30m/s, 45mph, etc). Those examples are examples of speed; it is only when we add a direction that it becomes 'velocity'. So, the difference is: "25m/s" is a speed, but "25m/s east" is a velocity. Speed (the magnitude of velocity) is calculated by taking the total displacement divided by the total time. Speed=(distance travelled)/(time it takes). Hope this helps

I belive she is a gold medalist at the Olympics in Discuss. So she excels in discuss throwing.
Who holds the discuss throw record?
Gabriele Reinsch of East Germany set the current discuss throwing world record of 251 ft. 11.6 in. in 1988.
Discuss the validity of extrapolating the acceleration value to an angle of 90?
Extrapolate the experimental values of acceleration, vs. angle of the incline, to find the acceleration when the angle of inclination = 90 degrees. The acceleration at 90 degrees will equal 9.81 m/s/s, since this is the free-fall acceleration.

Discuss effect of temperature on the velocity of sound?
Scroll down to related links and look at "Speed of sound - Wikipedia". There is a table of the effects of the temperature on sound. Don't say "velocity of sound", call it "speed of sound".
If the speed of a body remaining same discuss wheather its velocity can change?
Yes; if the direction changes (for instance, if an object moves in a circle), even if its speed doesn't change, its velocity changes. This is because the term "velocity" also includes the direction.

What is discuss throwing?
A discus is a round disc, like a frisbee but without a lip going around the edge. You throw it by spinning yourself and then using your arm to increase the momentum so you get maximum distance.
