Physic
a bullet is fired from at a shooting range. The bullet hits the ground after .32 seconds. How far did it travel horizontally and vertically in this time if it was fired at a velocity of 1100 m/s?

Physics
In the absence of air resistance, a projectile is launched from and returns to ground level. It follows a trajectory similar to that in the figure below and has a range of 15 m. Suppose the launch speed is doubled, and the projectile is fired at the same angle above the ground...

math
A projectile is launched vertically upward from the top of a 240-foot building. This translates to the model y = -16t^2 + 32t + 240 where y is the height in feet and t is the time in seconds after it was launched, When will the projectile hit the ground?
