A horizontal projectile is shot with an initial velocity of 29.7 m/s from a height of 3.18 m above the ground. Neglecting air resistance, how long it will take to reach the landing point (time in air measured in seconds)

A rock is launched over level ground with an initial velocity of 15.0 m/s at an angle of 20 degrees above the horizontal.  What is the projectile’s time of flight?

A Supply plane needs to drop a package of food to scientists working on a glacier in Greenland.  The plane flies 97 m above the glacier at a speed of 133 m/s.  How far away from the target should it drop the package? (Hint: This is a horizontal projectile. The package has the same initial speed as the plane)

A horizontal projectile is shot with an initial velocity of 21 m/s from a height of 6.3 m above the ground. Neglecting air-resistance, how long it will take to reach the landing point (time in the air measured in seconds)?

Two students are on a balcony 18.6 m above the street. One student throws a ball (ball 1) vertically downward at 13.1 m/s; at the same instant, the other student throws a ball (ball 2) vertically upward at the same speed. The second ball just misses the balcony on the way down. (a) What is the difference in the two ball's time in the air? (b) What is the velocity of each ball as it strikes the ground?

A stone is thrown horizontally with an initial speed of 10 m/s from the edge of a cliff. If the height of the cliff is 100 m, what is the time of flight of the stone if air resistance is negligibly small?

Juliet is standing in front of a wall and Romeo is at a window above her at a height of 3.61 m from the ground. Juliet tosses a box of candy straight up with speed 7.50 m/s from a height of 1.53 m above the ground. Ignore any effects due to air resistance. To receive full marks, you must include a diagram showing the physical situation and your choice of coordinate system. (a) Will the box reach Romeo? O Yes O No (b) If so, what is the box's speed when it reaches Romeo? If not, what initial speed must the rock have to reach Romeo? m/s

A ball of mass 500g and diameter 30 cm is thrown upward with an initial speed of 15.1m/s. If we include the effects of air resistance, what is the velocity of the ball after it has traveled three quarters the time it takes to reach its highest point?

A crossbow bolt is fired horizontally over level ground toward a target 37.4 m away. The bolt hits the target 0.24 m below the height at which it was fired.what was the initial speed of the bolt in m/s?

The highest barrier that a projectile can clear is 18.4 m, when the projectile is launched at an angle of 15.0° above the horizontal. What is the projectile's launch speed?
