In a chase scene, a movie stuntman is supposed to run right off the flat roof of one city building and land on another roof 1.9 m lower. If the gap between the buildings is 4.2 m wide, how fast must he run? Answer should be the velocity in m/s.
An object is thrown off of a cliff 320 m above level ground with an initial horizontal velocity of 20 m/s. How far from the building did the rock land?
The height (in meters) of a projectile shot vertically upward from a point 4 m above ground level with an initial velocity of 25.5 m/s is h = 4 + 25.5t − 4.9t2 after t seconds. When does the projectile meet its maximum height and what is its maximum height?
The height (in meters) of a projectile shot vertically upward from a point 3 m above ground level with an initial velocity of 22.5 m/s is h = 3 + 22.5t − 4.9t2 after t seconds. When does it hit the ground? With what velocity (in m/s) does it hit the ground?
An object is thrown from a level field with initial upward speed 17 m/s and forward speed 9.9 m/s. How far (in m) from its launch point is its landing place? You do not need to put the unit in the answer, just the number. As usual, ignore air resistance, etc; use the acceleration due to gravity as 9.8 meters per second squared.
