A ball rolls off a cliff at 5m/s. It takes 7 seconds to hit the ground. Solve for the following variables.
y=
Vfy=
dx=
An airplane is flying horizontally at 200m/s needs to drop a package on a target. How far behind the target should the plane be when it releases the package if it is flying 500m in the air?
An astronaut on planet Kobol throws a rock horizontally with a speed of 5.25m/s. The rock falls a vertical distance of 2.23m and lands a distance off 9.5m away from the astronaut. What is the acceleration due to gravity on Kobol?
An object is launched at a 25 degree angle at 20m/s. Find the total hang time, Vx, Viy, and range of the projectile.
A golf ball is struck with a driver on level ground. It lands 275m away 9.78s later. What is the direction and magnitude of the initial velocity?
A projectile is launched with an initial speed of V. At its highest point its speed is V/2. What is the launch angle?
A projectile is launched off a 20m tall building. Using the information in the diagram determine how far away from the building the projectile will land.
V=12m/s at 55 degree angle.
A young girl swings on a rope above a local swimming hole. When she lets go of the rope her initial velocity is 3.0m/s at an angle of 30 degrees above the horizontal. If she is in flight for 1.2s, how high above the water was she when she let go of the rope?
