Chapter 09, Problem 059 In the figure, block 1 (mass 3.7 kg) is moving rightward at 6.5 ms and block 2 (mass 4.1 kg) is moving rightward at 1.0 m/s. The surface is frictionless, and a spring with a spring constant of k=860 N/m is fixed to block 2. When the blocks collide, the compression of the spring is maximum at the instant the blocks have the same velocity. Find the maximum compression. irono Number Units The number of significant...

In the figure, block A (mass 1.2 kg) slides into block B (mass 2.7 kg), along a frictionless surface. The directions of velocities before and after the collision are indicated; the corresponding speeds are vAI = 5.7 m/s, vBi = 2.3 m/s, and vBf = 4.1 m/s. What is velocity vAf (including sign, where positive denotes motion to the right)? VB Units Number The number of siqnificant digits is set to 2; the tolerance is +/-3%

Let’s begin by calculating the total momentum of two moving
objects. Suppose a small compact car with a mass of 1000 kg is
traveling north on Morewood Avenue at a speed of 15 m/sm/s. At the
intersection of Morewood and Fifth Avenues, it collides with a
truck with a mass of 2000 kg that is traveling east on Fifth Avenue
at 10 m/sm/s. Treating each vehicle as a particle, find the total
momentum (magnitude and direction) just before the collision....

Chapter 08, Problem 009 In the figure, a frictionless roller coaster car of mass m = 830 kg tops the first hill with speed vo = 17.0 m/s at height h = 43.0 m, what is the speed of the car at (a) point A, (b) point B, and (c) point C? (d) How high will the car go on the last hill, which is too high for it to cross? Use g-9.81 m/s2. 0 First hill h/2 (a) Number...

(a) At what speed (in m/s) would a 2.77 x 104 kg airplane have to fly to have a momentum of 1.31 x 109 kg m/s (similar to the momentum of a large moving ship)? m/s (b) What is the plane's momentum (in kg m/s) when it is taking off at a speed of 55.3 m/s? kg m/s (c) If the ship is an aircraft carrier that launches these airplanes with a catapult, discuss the implications of your answer to...
