Question

Will mark Brainliest!! Watson, a mountaineer, attempts to jump over a ravine that is 7 meters wide and 10 meters deep within 2 seconds to escape an approaching avalanche. Calculate the minimum speed with which he should attempt the jump so that he safely gets to the other side of the ravine.

Answer 1

V=distance/time
v=7m/2s
v=3.5m/s

Answer 2

Answer:

Watson's minimum speed, s = 3.5 m/s

Explanation:

It is given that, Watson, a mountaineer attempts to jump over a ravine that is 7 meters wide and 10 meters deep within 2 seconds to escape an approaching avalanche.

We have to find the minimum speed with which he should attempt the jump so that he safely gets to the other side of the ravine.

Speed is given by :

$s=\dfrac{d}{t}$

d is the distance, d = 7 m

$s=\dfrac{7\ m}{2\ s}$

s = 3.5 m/s

Hence, his minimum speed so that he safely gets to the other side of the ravine is 3.5 m/s
