A projectile is fired from the ground, reaches a maximum height of 50.8 m and lands a distance of 39.1 m away from the launch point. What was the projectile s launch velocity? You launch a projectile toward a tall building, from a position on the ground 39.3 m away from the base of the building. The projectile s initial velocity is 45.9 m/s at an angle of 58.7 degrees above the horizontal. At what height above the ground does...

The projectile s initial velocity is 34.4 m/s at an angle of 57.5 degrees above the horizontal. At what height above the ground does the projectile strike the building? 76.1 m 60.9 m 19.9 m 37.5 m
To practice Problem-Solving Strategy 4.1 for projectile motion problems. A rock thrown with speed 6.00 m/s and launch angle 30.0 ∘ (above the horizontal) travels a horizontal distance of d = 19.5 m before hitting the ground. From what height was the rock thrown? Use the value g = 9.800 m/s2 for the free-fall acceleration. Find the height yi from which the rock was launched.
A projectile is launched from the top of a cliff at an angle of 45 degrees and with a velocity of 600 m/s. See Figure 1. What will be the height of the projectile at a distance of 1500 m from the launch point? What will be the distance, d1, from the launch point when the projectile will have a velocity vector at an angle of 60 degrees below the horizontal?
If a projectile is fired with an initial velocity of v0 meters per second at an angle α above the horizontal, and air resistance is assumed to be negligible, then its position after t seconds is given by the parametric equationsx=(v0 cos α) t y=(v0 sin α) t-1/2 g t2where g is the acceleration due to gravity (9.8 m / s2)(a) If a projectile is fired with α=45° and v0=900 m / s, when will it hit the ground? How...
