3) Object A (m 5 kg) moving at 1 m/s moves toward a stationary object B...
An object (A) of mass m A = 29.0 kg is moving in a direction that makes angle of 40° north of east with a speed v A = 5.10 m/s, while object (B) of mass m B = 17.5 kg is moving due north with a speed v B = 7.85 m/s. The two objects collide and stick together in a completely inelastic collision. Find the magnitude of the final velocity of the two-object system after the collision. An...
11.9. As shown in the figure, an object of charge Q, and mass m moves near a stationary object with charge Q2. Assume the mass and the charges are constants, and assume the objects are surrounded by free space. The kinetic energy of the moving object is converted to or from energy stored in the electric field between the objects. The kinetic energy of the moving object is given by m). The energy of the electric field is given by...
3. An 4.0-kg object moving 2.1 m/s in the positive x direction has a one-dimensional collision with a 2.0-kg object moving 3.2 m/s in the opposite direction. Assuming the collision is frictionless. The final velocity of the 2.0-kg object is 2.1 m/s in the positive x direction. What is the final velocity of the 4.0 kg object? (0pts)
A(n) 5 kg object moving with a speed of 6.8 m/s collides with a(n) 19 kg object moving with a velocity of 9.1 m/s in a direction 18 degree from the initial direction of motion of the 5 kg object. What is the speed of the two objects after the collision if they remain stuck together? Answer in units of m/s. What is the change in direction experienced by the lighter of the two objects? Answer in units of degree.
A moving object A of mass 8.7 kg and speed 2.2 m/s collides with a stationary object B of mass 9.4 kg. The collision is totally inelastic. Calculate the speed of the combined object after collision.
An object (A) of mass mAA = 27.5 kg is moving in a direction that makes angle of 56° south of east with a speed vAA = 5.00 m/s, while object (B) of mass mBB = 17.5 kg is moving due north with a speed vBB = 8.00 m/s. The two objects collide and stick together in a completely inelastic collision. Find the magnitude of the final velocity of the two-object system after the collision.
A 4.0 kg object is moving at 5.0 m/s NORTH. It strikes a 6.0 kg object at rest. The objects have an elastic collision and move in the NORTH or SOUTH direction. The velocity of the 6.0 kg object after the collision is
10. A 2kg object moving at 10 m/s to the right strikes a stationary 3kg object. After the collision the 2 kg object is moving to the left at 2 m/s, while the 3kg object is moving to the right at 8 m/s. Is this collision elastic?
68. Object A with mass 8.0 kg travels to the east at 10.0 m/s and object B with mass 3.0 kg travels south at 20.0 m/s. The two objects collide and stick together as shown below. What is the magnitude of the velocity they have after the collision? What is the direction of the velocity they have after the collision? 1- 10 m/s
1. A stationary refrigerator car with mass 2.0 x 104 kg is rammed by a loaded gondola car with mass 3.0 x104 kg. Before the impact, the gondola car was going 1.0 m/s. If they lock together, what is the new velocity? 2. A force of 30 N accelerates a 2.0 kg object from rest for a distance of 3.0 m along with a level, frictionless surface; the force then changes to 15 N and acts for an additional 2.0...
