For general projectile motion with no air resistance, the horizontal component of a projectile's velocity continuously increases. first decreases and then increases. O continuously decreases. remains a non-zero constant. remains zero.

A shot fired from a gun with a muzzle speed of 1200 feet per second is to hit a target 3000 feet away. Determine the minimum angle of elevation of the gun .Use the model for projectile motion, assuming there is no air resistance and g = 32 feet per second per second.

9. If a projectile (such as a bullet) is fired into the air with an initial velocity v at an angle of elevation of θ (see the figure), then the height h of the projectile at time t is given by

7. A basketball player is running at 4.80 m/s directly toward the basket when he jumps into the air to dunk the ball. He maintains his horizontal velocity. (For each answer, enter a number.) (a) What vertical velocity (in m/s) does he need to rise 0.750 meters above the floor? m/s (b) How far (in m) from the basket (measured in the horizontal direction) must he start his jump to reach his maximum height at the same time as he reaches the basket? m Submit Opcwor
