Chapter 7, Problem 1CQ
You find yourself in the middle of a frozen lake with a surface so slippery
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.
We can understand this with the below free body diagram.
Figure.1
Conclusion:
On a frictionless surface, if anybody wants to move in a certain direction than he/she must throw something in the opposite direction.

You have just landed on Planet X. You release a 180 gg ball from rest from a height of 10.0 mm and measure that it takes 3.40 ss to reach the ground. Ignore any force on the ball from the atmosphere of the planet.
A.
How much does the 180 gg ball weigh on the surface of Planet X?
Express your answer with the appropriate 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.

You try your idea on a glass surface and a glass cup (mass = 0.15 kg). You set the glass cup moving with an initial speed of 2.8 m/s. After travelling a length of 1 m, it stopped.

- You and four of your friends are all interested in getting out of town for a break. Two of your friends just want to relax while the other two want to get some exercise. You need some quiet time to study. To satisfy everyone, the group decides to spend the day canoeing on the river. Two people will put a canoe in the river and just drift downstream with the 1.5 km/h current. The second pair will begin at the same time as the first from 10. km downstream. They will paddle upstream until the two canoes meet. Since you have been canoeing with these people before, you know that they can paddle at 4.0 km/h in still water. When the two canoes meet, they will come to shore and you should be there to meet them with the picnic lunch. You decide to go to that spot ahead of time so you can study while you wait for your friends. How far from where the drifters launched will you wait for them? After lunch you decide to paddle across the river, which is 0.50 km wide. You can paddle 3.0 km/h in…arrow_forwardOne of the complicating factors in analyzing motion is the presence of friction. It is difficult to isolate the effect of friction and to imagine what motion looks like without it. Newton's 2nd law of motion states that a force applied to a mass will cause an acceleration, f = ma. UNLESS THE PROBLEM STATES OTHERWISE, assume the experiments below are performed on a surface of smooth ice so that the effect of friction is negligible. 1) a. Imagine a cube-shaped mass of 100 kg. If two people push it to the right, one with a force of 150 N, and one with a force of 220 N, what acceleration should the cube experience? b.
