Chapter 10: Q.4 (page 255)

The three balls in FIGURE Q10.4, which have equal masses, are fired with equal speeds from the same height above the ground. Rank in order, from largest to smallest, their speeds va, vb, and vc as they hit the ground. Explain.

Short Answer

Expert verified

All of the speeds as they reach the ground are the same.

Step by step solution

01

Content Introduction

Kinetic energy is a type of energy that may be exchanged between objects and converted into other forms of energy. The quantity of kinetic energy that an object has is determined by two variables: the object's mass (m) and its speed (v).

02

Content Explanation

Three balls with equal masses will hit the ground at the same speed because they have the same starting Kinetic Energy, and the direction of speed (v0) won't change that.

In Problems 66 through 68you are given the equation used to solve a problem. For each of these, you are to

a. Write a realistic problem for which this is the correct equation.

b. Draw the before-and-after pictorial representation.

c. Finish the solution of the problem.

12(1500kg)(5.0m/s)2+(1500kg)9.80m/s2(10m)=12(1500kg)vi2+(1500kg)9.80m/s2(0m)

A cable with 20.0N of tension pulls straight up on a 1.50kg block that is initially at rest. What is the block鈥檚 speed after being lifted 2.00m? Solve this problem using work and energy.

FIGUREEX10.24is the potential-energy diagram for a 20g particle that is released from rest at x=1.0m.

a. Will the particle move to the right or to the left?

b. What is the particle鈥檚 maximum speed? At what position does it have this speed?

c. Where are the turning points of the motion?

It鈥檚 your birthday, and to celebrate you鈥檙e going to make your first bungee jump. You stand on a bridge 100mabove a raging river and attach a 30m-long bungee cord to your harness. A bungee cord, for practical purposes, is just a long spring, and this cord has a spring constant of 40N/m. Assume that your mass is 80kg. After a long hesitation, you dive off the bridge. How far are you above the water when the cord reaches its maximum elongation?

The spring in FIGURE CP10.73 has a spring constant of 1000N/m. It is compressed 15cm, then launches a 200gblock. The horizontal surface is frictionless, but the block鈥檚 coefficient of kinetic friction on the incline is 0.20. What distance d does the block sail through the air?
