A) Define: average velocity and speed, instantaneous velocity and acceleration.?

(a) Define: average velocity and speed, instantaneous velocity and acceleration.


(b) Define the velocity and position of a projectile. A projectile has the least speed at what point in its path? Explain.


(c) Describe uniform circular motion and determine the velocity and acceleration of an object which executes this motion.


(d) A tiger leaps horizontally from a 16m high rock with a speed of 7.0 m/s. How far from the base of the rock will it land?

A) Define: average velocity and speed, instantaneous velocity and acceleration.?
average velocity/speed refers to difference between the initial and the final and the average.





instantaneious refers to the given speed at any given instant.





A projectile has the least amount of speed once it has reached it's highest point which is ZERO before it accelerates back to the ground.





d) t = square root of 2d/a


t = square root of 2(16m) / 9.80m/s^2


t = 3.26s





v = d /t


d = v*t


d = 7m/s * 3.26s = 22.9m
