A70.0-kg skier is sliding at 4 m/s when they slide down a 2m high hill. at the bottom of the hill they run into a large 2800 n/m spring.

how far do they compress the spring before coming momentarily to rest? ignore friction.

Explanation:

Given:

final velocity of skier before coming in contact of spring:

Using eq. of motion:

Now the time taken by the skier to reach down:

Now we calculate force using Newton's second law:

∴Compression in spring before the skier momentarily comes to rest:

answer: the correct answer is   air pressure at the top of mount everest is higher than at the bottom of the grand canyon.

hope this : )
