Question

an archer shoots an arrow horizontally with an initial velocity of 100 M per second from a building that is 20 m high (air resistance is neglected). The time when the arrow is in the air and the horizontal distance that the arrow Travels before striking the ground is

Answer 1

Answer:

for the total time that particle is on air= √2h/g

so, √2×20÷20=2s

and for the total horizontal distance which is equal to range we have the relation t=r/u

so,. 2×100=200m

Hope that helps
