An arrow is shot horizontally from a 70 m high building. It lands on the ground 145 m from the bottom of the building. What was the initial velocity of the arrow? A) 20.3 m/s B) 38.4 m/s C) 14.8 m/s D) 54.2 m/s E) 3.8 m/s

Step 1
First, we need to find the time it takes for the arrow to hit the ground. Since the arrow is shot horizontally, we can use the vertical motion to find the time. We know the initial vertical velocity is 0 m/s, the height is 70 m, and the acceleration due to gravity Show more…

You launch a projectile toward a tall building, from a position on the ground 32.4 m away from the base of the building. The projectile s initial velocity is 34.2 m/s at an angle of 43.5 degrees above the horizontal. At what height above the ground does the projectile strike the building? a. 22.4 m b. 51.8 m c. 41.4 m d. 13.0 m

A projectile is launched horizontally from a $12.4-\mathrm{m}$ -tall building at $14.0 \mathrm{~m} / \mathrm{s} .$ How far (horizontally) from the base of the building does it strike the ground? (a) $22.3 \mathrm{~m}$ (b) $17.7 \mathrm{~m}$; (c) $12.4 \mathrm{~m}$ (d) $10.9 \mathrm{~m}$
An arrow is shot from the edge of a cliff at 46 m/s at 20 degrees above the horizontal. If it lands at a distance of 281 m from the base of the cliff, then what is the height of the cliff? a. 145 m b. 191 m c. 59 m d. 105 m
