A person throws a stone with a velocity 10m/s at angle tan 0= 3/4 to horizontal
from a point at a distance 8m from the wall. The stone just passes over the
wall. The height of the wall is (g= 10m/s2)

Answer:
Hey mate !
PLEASE SEND A PERFECT QUESTION
I DON'T THINK SO IT'S A PERFECT QUESTION BECAUSE
Answer:
1.8m
Explanation:
tanø=3/4 → sinø=3/5( 3,4,5 Pythagoras theorem)
v=10m/s
H=u²sin²ø/2g
H=100*9/25*2*10
H=9/5= 1.8m
