A 5 kg cart moving at a velocity 2 m/s in the +x-direction collides completely inelastically (i.e. they stick) with a second cart of mass 1.5 kg which is initially moving at a velocity of 10 m/s in the +y-direction. What is the total initial kinetic energy? J. What is the total x-component of momentum just before the collision? Kg m/s. What is the total y-component of momentum just before the collision? Kg m/s. What is the total x-component of momentum just after...
A mass is moving at 8 m/s in the +x direction and it collides in a perfectly elastic collision with a mass of 3 kg moving in the -x direction. The collision takes places in 0.21 seconds and after the collision the mass that was moving in the +x direction is moving in the -x direction at 9 m/s and the mass that was moving in the -x direction is moving in the +x direction at 11 m/s. What is...
A mass of 2.5 kg moving at 5.5 m/s collides with a stationary object of mass 4.6 kg. After collision, they move off together. Calculate the final speed in m/s, to 2 sf.
PART A A particle of mass 2.5 kg is moving with v =(-2.3i+1.4j )(m/s). At one instant,it is located at r = (2i+4j) m. Calculate the angular momentum of the particle at that instant with respect to the origin. Answer: 30 kgm2/s? PART B Find the angular momentum of a solid cylinder rotating with 12 rad/s angular speed around the axis passing through its center of mass. The radius of the cylinder is 15 cm, its length is 30 cm...
A mass of 5 kg is moving at 16 m/s in the +x direction and collides in a perfect elastic collision with a 2 kg mass moving in the +x direction at 10 m/s. If the masses are in contact for 0.15 seconds, what is the average force on the 5 kg mass in Newtons? Include a negative sign if in the negative x direction.
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...
A mass of 5 kg is moving at 8.2 m/s in the positive x direction and collides in a perfectly elastic collision with a second mass which is not at rest. After the collision, the second mass is moving at 12.3 m/s in the +x direction. If the 5 kg mass stops after the collision, what is the amount of the second mass in kg?
