What Is It? • Two dimensional motion resulting from a vertical acceleration due to gravity and a uniform horizontal velocity
Separate • Galileo determined that the vertical and horizontal components of the projectile motion can be analyzed separately • Acceleration due to gravity is the same regardless of horizontalvelocity • An object projected horizontally will reach the ground at the same time as one dropped straight down from the same height
Example 1 • A student driver on a motorcycle speeds horizontally off a 50.0m high cliff. How fast must the motorcycle leave the top if it is to land 90m from the base of the cliff?
Example 2 • A football is kicked at an angle of 37° with a velocity of 20m/s. Calculate a) the max height b) the time to hit the ground c) how far away it hits d) velocity at max height e) acceleration at max height
