1. how long does it take to fall 160m? The horizontal speed does not affect that.

4.9t^2 = 160

Now, the horizontal speed does not change, so the body travels

20t meters

2. what if i said it is u=20 h=160
20/10=2m/s 160/10=16
t=8m/s
1.time of flight =8m/s 16/2=8m/s
2.distance=20*10=200/10=2
distance
=2*10/10=2mls
H=8m/s
V=2m/s

thats how i got my answer collect me if am worng
