10. A mountain climber encounters a crevasse in an ice field. The opposite side of the crevasse is 2.75m lower, and the horizontal gap is 4.1m. To cross the crevasse, the climber gets a running start and jumps horizontally. a) What is the minimum speed vo needed for the climber to cross the crevasse? b) Suppose the climber jumps at 6m/s, where does he land? c) What is his speed on landing?

This is all 1 question

So, how do I get to the final answer?

There is at least one more.

Can someone explain this again... Thank you.

Only the first 3 parts were answered. Still need help with the last 3

the options for the question are 2,700 - 27,000 - 1,400 - 14,000

Would the answer be 2.7? (#40 please)

In the number 24330 which of the following is the least significant digit? Answer: 0 x

Three particles with charges q₁ = +10 μC, q₂ = -20 μC and q3 = +30 μC, are positioned at the vertices of an isosceles triangle with sides a = 0.1 m b = 0.06 m as shown in the Figure. How much work must we do to exchange the positions of q₁ and q3 ? Give your answer in Joules. Hint: What is the Energy of the system of 3 charges as they are and what is its Energy when the positions of 91 and 93 are exchanged? What does the difference between these energies represent?
