Question

A shot is fired horizontally with a velocity of 900 m/s from the top of a tower 100 m high. Find the distance from the foot of the tower where it strikes the ground. (g=9.8 m/s)​

Answer 1

Answer:

Explanation:

Given :    u  

x

​

=98m/s               a  

y

​

=g=9.8m/s  

2

 

Height of the hill          S  

y

​

=h=490  m

∴  Time of flight      T=  

g

2h

​

 

​

=  

9.8

2(490)

​

 

​

=10  s

Distance   BA (or horizontal range)        BA=u  

x

​

T=98×10=980m
