Answer:
5.9 m
Explanation:
v=6m/s
H=5m
h=0.17m
g=10 m/s
First we find the time in which ball reaches the entrance of coffee can. For this purpose the ball has to travel a distance S vertically downward such that
S= 5-0.17 = 4.83 m
While falling down Vi =0
g= 10 m/sec2
t = ?
S=vit+1/2 gt2
==> 4.83=0+0.5×10×
==> 4.83=5×
==> =4.83/5 = 0.97
==> t= 0.98 sec
So in this time the ball reaches the coffee can height level. Now let's calculate horizontal distance covered by the ball in this time.
Horizontal distance = horizantal velocity × time
= 6 × 0.98 = 5.9 m
