Answer:
0.25hr
Explanation:
Given parameters:
Distance = 200km
Time = 2hrs
Now, let us find the rate which is the speed;
Speed =
Insert parameters:
Speed =
= 100km/hr
Since the speed of Imamu = 2 x speed of Mosi = 200km/hr
Time taken =
=
= 0.25hr
To solve this question you need to find the time span of the ski jumper before he lands
thus
25 = 1/2*10*t^2
50/10 = t^2
t = 2.23 seconds
and the distance is given 135m
speed = distance/time
= 135/2.23
= 60.5 m/s
