Chapter 18, Problem 21 Interactive LearningWare 18.2 provides one approach to solving problems such as this one. The drawing shows three point charges fixed in place. The charge at the coordinate origin has a value of q1 = +6.051C; the other two have identical magnitudes, but opposite signs: q2 = -4.8ß1C and q3 = +4.80 . (a) Determine the net force exerted on q1 by the other two charges. (b) Ifq1 had a mass of 1.50 g and it were...

Chapter 09, Problem 57 Chalkboard Video A bowling ball encounters a 0.760-m vertical rise on the way back to the ball rack, as the drawing illustrates. Ignore frictional losses and assume that the mass of the ball is distributed uniformly. The translational speed of the ball is 5.57 m/s at the bottom of the rise. Find the translational speed at the top. Units Number

Chapter 07, Problem 42 GO Chalkboard Video A 6.80-g bullet is moving horizontally with a velocity of +346 m/s, where the sign + indicates that it is moving to the right (see part a of the drawing). The bullet is approaching two blocks resting on a horizontal frictionless surface. Air resistance is negligible. The bullet passes completely through the first block (an inelastic collision) and embeds itself in the second one, as indicated in part b. Note that both blocks...

Chapter 03, Problem 35 Chalkboard Video A rocket is fired at a speed of 61.0 m/s from ground level, at an angle of 75.0 above the horizontal. The rocket is fired toward an 47.0-m high wall, which is located 19.0 m away. The rocket attains its launch speed in a negligibly short period of time, after which its engines shut down and the rocket coasts. By how much does the rocket clear the top of the wall? 1 Units Number...

Chapter 09, Problem 83 Chalkboard Video Two spheres are each rotating at an angular speed of 21.9 rad/s about axes that pass through their centers. Each has a radius of 0.430 m and a mass of 1.66 kg. However, as the figure shows, one is solid and the other is a thin-walled spherical shell. Suddenly, a net external torque due to friction (magnitude-0.1 20 N·m) begins to act on each sphere and slows the motion down. How long does it...
