Question

Two water jets are emerging from a vessel at a height of 50 centimeters and 100 centimeters. If their horizontal velocities at the point of ejection are 1 meter/second and 0.5 meters/second respectively, calculate the ratio of their horizontal distances of impact.

Answer 1

1.41:1

Step-by-step explanation:

Answer 2

t1 = √2h1/g = √2*0.5/9,8 = 0.319 sec
t2 = √2h2/g = √2*1.0/9,8 = 0.451 sec

In which t = times for the vertical movement
h = height
g= gravity (we use standardized measurement of 9.8)

d1 = 1*0.319 = 0.319 m
d2 = 0.5*0.451 = 0.225 m

in which d = Horizontal distance

ratio
= di : d2
= 0.319 : 0.225

= 3.19 : 2.25
