You find yourself in the middle of a frozen lake with a surface so slippery ( µ s = µ k = 0 ) you cannot walk. However, you happen to have several rocks in your pocket. The ice is extremely hard. It cannot be chipped, and the rocks slip on it just as much as your feet do. Can you think of a way to get to shore? Use pictures, forces, and Newton's laws to explain your reasoning.

You find yourself in the middle of a frozen lake with a surface so slippery ( µ s = µ k = 0 ) you cannot walk. However, you happen to have several rocks in your pocket. The ice is extremely hard. It cannot be chipped, and the rocks slip on it just as much as your feet do. Can you think of a way to get to shore? Use pictures, forces, and Newton's laws to explain your reasoning.

Expert Solution & Answer

To determine

The way to get to the shore in the given situation.

Explanation of Solution

This is according to Newton’s third law which says that to every action there is an equal and opposite reaction. So, if we throw the rock with a force in the opposite direction as an action then rocks also apply force on us in the direction of their movement.

Conclusion:

On a frictionless surface, if anybody wants to move in a certain direction than he/she must throw something in the opposite direction.

A person whose weight is 508 N is being pulled up vertically by a rope from the bottom of a cave that is 39.5 m deep. The maximum tension that the rope can withstand without breaking is 588 N. What is the shortest time, starting from rest, in which the person can be brought out of the cave? Number i Units +

A student suggests that the force of air resistance FA depends on the relative speed of an object passing through the air v according to FA = kvN, where k is a constant with appropriate units that depends on properties of the air and the size and shape of the object and N is a dimensionless exponent. The student has a hollow ball made of two hemispherical shells that can be connected together and disconnected, along with access to other commonly available materials. Write an experimental procedure that the student could follow to make measurements in order to find the value of N, and explain how a graph of In(FA) vs. In(v) could be used to find the values of k and N.
