Chapter 1: Q4-35DQ (page 123)

When a car is hit from behind, the occupants may experience whiplash. Use Newton鈥檚 laws of motion to explain what causes this result.

Short Answer

Expert verified

Passengers in a car which is suddenly hit from behind may experience a whiplash due to inertia of rest.

Step by step solution

01

Concept of inertia of rest

A body in rest tends to be in rest unless an external force acts on it.

02

Reason for occupants experiencing a whiplash when the car is hit from behind

When a car is suddenly hit from behind it moves forward in a sudden motion. The body of the passengers tend to stay in their initial position due to inertia of rest. This causes the passengers to experience a whiplash.

A hammer with mass m is dropped from rest from a height h above the earth鈥檚 surface. This height is not necessarily small compared with the radiusof the earth. Ignoring air resistance, derive an expression for the speed v of the hammer when it reaches the earth鈥檚 surface. Your expression should involve h,, and(the earth鈥檚 mass).

In 2005 astronomers announced the discovery of large black hole in the galaxy Markarian 766 having clumps of matter orbiting around once every27鈥�hours and moving at30,000鈥�km/s . (a) How far these clumps from the center of the black hole? (b) What is the mass of this black hole, assuming circular orbits? Express your answer in kilogram and as a multiple of sun鈥檚 mass. (c) What is the radius of event horizon?

Can you find two vectors with different lengths that have a vector sum of zero? What length restrictions are required for three vectors to have a vector sum of zero? Explain.

A medical technician is trying to determine what percentage of a patient鈥檚 artery is blocked by plaque. To do this, she measures the blood pressure just before the region of blockage and finds that it is 1.20脳104Pa, while in the region of blockage it is role="math" localid="1668168100834" 1.15脳104Pa. Furthermore, she knows that blood flowing through the normal artery just before the point of blockage is traveling at 30.0 cm/s, and the specific gravity of this patient鈥檚 blood is 1.06. What percentage of the cross-sectional area of the patient鈥檚 artery is blocked by the plaque?
