- Two vehicles are approaching an intersection. One is a 2500 kgkg pickup traveling at 15.0 m/sm/s from east to west (the −x−x-direction), and the other is a 1600 kgkg sedan going from south to north (the +y+y-direction at 25.0 m/sm/s). Find the xx-component of the net momentum of this system. Express your answer in kilogram meters per second. Find the yy-component of the net momentum of this system. Express your answer in kilogram meters per second.Four particles are arranged in a square with sides of 1.0 m. The bottom particles each have a mass of 1.0 kg. The center of mass of the system is located at Ycm = 0.25 m. The upper particles each have mass m. What is m?A fire hose sprays water against a burning building. The stream of water has cross-sectional area A and density ρ and moves with speed v toward the building. Assume the water splatters against the building without reflecting. What magnitude of impulse does the stream of water deliver during the time interval Δt? Express your answer in terms of the variables A, ρ, v, and Δt.
- Under many conditions, the center of mass of a system of particles can represent the system as a whole. But how far does this rule extend? Consider two identical particles traveling toward each other at the same speed. By examining this system, choose the correct response. 1)The momentum and kinetic energy of the center of mass is equivalent to that of the system of particles. 2)The kinetic energy, but not the momentum, of the center of mass is equivalent to that of the system of particles. 3)Neither the momentum nor the kinetic energy of the center of mass is equivalent to that of the system of particles. 4)The momentum, but not the kinetic energy, of the center of mass, is equivalent to that of the system of particles.In a hydrochloric acid (HCI) molecule, the distance between the hydrogen atom and the chlorine atom is 1.27 x 10 10 meters. The mass of an hydrogen atom is 2 atomic mass units (amu) and the mass of a chlorine atom is 35 amu. How far from the hydrogen (H) atom is the center of mass of the molecule, in meters? Justify your answer using your equations and rationale used.A watermelon is blown into three pieces by a large firecracker. Two pieces of equal mass m fly away perpendicular to one another, one in the x direction another in the y direction. Both of these pieces fly away with a speed of V = 23 m/s. The third piece has three times the mass of the other two pieces. Write an expression for the speed of the larger piece, that is in terms of only the variable V. What is the numeric value for the speed of the larger piece, in meters per second? At what angle does the largest piece travel with respect to the -y axis, in degrees?

- Two objects collide head-on (see figure below). The first object is moving with an initial speed of v1i = 7.94 m/s and the second object is moving with an initial speed of v2i = 10.00 m/s. Assuming the collision is elastic, m1 = 5.17 kg, and m2 = 6.29 kg, determine the final velocity of each object. (Indicate the direction with the sign of your answer. Positive is to the right, and negative is to the left. Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.)Two balls of clay, with masses M1 = 0.39 kg and M2 = 0.42 kg, are thrown at each other and stick when they collide.
