1. an airow is shot horizontally from a crossbow 1.5 m above the ground. the initial velocity is 45
m/s. how long will the arrow travel through the air before hitting the ground?

Time taken by the arrow to travel along to hit the ground is 0.55 seconds.

Explanation:

The only "force" acting on the "crossbow" to cause it to "hit" the ground is "gravity". There is no initial velocity downward when it shoot.

d = the displacement of the object  

t = the time for which the object moved  

a = acceleration of the object  

= the initial velocity of the object

Given values

d = 1.5 m

t = unknown

Square root both sides

t = 0.55 s
