Chapter 7: Q28Q (page 170)

A rocket following a parabolic path through the air suddenly explodes into many pieces. What can you say about the motion of this system of pieces?

Short Answer

Expert verified

The motion of the exploded particles is towards the original path of the rocket before it exploded.

Step by step solution

01

Understanding the path of the rocket before the explosion

The rocket follows the parabolic path before the explosion due to the presence of the force of gravity.

02

Identifying the motion of the pieces of the rocket after the explosion

As the rocket explodes in the air, all the pieces follow separate parabolic paths. An internal force caused the rocket to explode, so it does not change the motion of the center of mass of the exploded pieces. Hence, the center of mass of all the pieces follows the original path of the rocket, i.e., the path before the explosion.

A 95-kg fullback is running at \({\bf{3}}{\bf{.0}}\;{{\bf{m}} \mathord{\left/{\vphantom {{\bf{m}} {\bf{s}}}} \right.\\} {\bf{s}}}\) to the east and is stopped in 0.85 s by a head-on tackle by a tackler running due west. Calculate

(a) the original momentum of the fullback,

(b) the impulse exerted on the fullback,

(c) the impulse exerted on the tackler, and

(d) the average force exerted on the tackler.

(I) The distance between a carbon atom \(\left( {{\bf{m = 12}}\;{\bf{u}}} \right)\) and an oxygen atom \(\left( {{\bf{m = 16}}\;{\bf{u}}} \right)\) in the CO molecule is \({\bf{1}}{\bf{.13 \times 1}}{{\bf{0}}^{{\bf{10}}}}\;{\bf{m}}\) How far from the carbon atom is the center of mass of the molecule?

A light object and a heavy object have the same kinetic energy. Which has the greater momentum? Explain.

A bullet of mass \(m{\bf{ = 0}}{\bf{.0010}}\;{\bf{kg}}\) embeds itself in a wooden block with mass \(M{\bf{ = 0}}{\bf{.999}}\;{\bf{kg}}\), which then compresses a spring \(\left( {k{\bf{ = 140}}\;{\bf{N/m}}} \right)\) by a distance \(x{\bf{ = 0}}{\bf{.050}}\;{\bf{m}}\) before coming to rest. The coefficient of kinetic friction between the block and table is \(\mu {\bf{ = 0}}{\bf{.50}}\).

(a) What is the initial velocity (assumed horizontal) of the bullet?

(b) What fraction of the bullet's initial kinetic energy is dissipated (in damage to the wooden block, rising temperature, etc.) in the collision between the bullet and the block?

The speed of a tennis ball on the return of a serve can be just as fast as the serve, even though the racket isn鈥檛 swung very fast. How can this be?
