What is the vertical velocity at the peak of a projectile's trajectory?
What is ZERO!
Horizontal Velocity is always
Constant
If Jasper threw a tennis ball off a 10-meter cliff, How long would it take for the ball to hit the ground?
1.4 s
Define Trajectory
It is the path of a projectile
If Jasper threw the ball at 5m/s. Where would the ball land with respect to the cliff?
Remember t=1.4
7 meters away from the cliff
How much will the horizontal velocity change in 19.6 seconds?
None at ALL
Y can be determined by multiplying the acceleration due to gravity by ________________.
Y=viy(t)+0.5 ay t2
Rolyna was the cavewoman from the physics story, she rolled a pumpkin at 2m/s off a cliff to hit the lion below. The cliff was 15 meters high. How long was the pumpkin in the air?
1.7s
If you drop a bullet while firing a bullet from a gun at the same time and height, which would hit the ground first?
They would both hit the ground at the same time.
What is the acceleration for a projectile in the y-direction?
What is 9.8m/s2
What is the acceleration for an object in the y direction?
9.8m/s2
Daily Double
Write the variable that stands for initial velocity in the horizontal direction.
Vix
EXPLAIN where AND how a package dropped from a plane lands with respect to the moving plane.
The package ends up UNDER the moving plane, since its horizontal velocity remains constant.
