Question

(16)A ball is throw straight up with enough speed so that it is in the air for several seconds ( hint – please read ch.2 and go over the image/chart of a ball being tossed in the air. Make sure you know the difference between acceleration and velocty

a-) Distinguish between velocity and acceleration.

Apply each to a ball being tossed upward:

b-)What is the velocity of the ball when it reaches its highest point?

c-)What is the velocity 1sec before it reaches its highest point?

d-)What is the change in velocity during this 1-s interval before it reaches the highest point?

e-)What is the velocity 1 sec after it reaches its highest point?

f-)What is the change in velocity during this 1-sec interval after reaching its highest point?

g-)What is the change in velocity during the 2 sec interval from 1 se before the highest point to 1 sec after its highest point( caution, I am asking for velocity, not speed)

h-)What is the acceleration of the ball during any of these time intervals and at the moment the ball has 0 velocity at the top of its path?

i-)Draw a Diagram of what is happening and label it with all of the answers determined in b-h.

Explanation / Answer

1. Velocity is change in distance travelled per unit time and Acceleration is change in velocity per unit time.

2. At the highest point the velocity is zero.
