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.

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).
What organizational pattern do you move back and forth between subjects as you discuss different features?
Point by point organization.
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.
