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...
3) A mass of 9 kg is moving at 9 m/s in the +x direction which collides inelastically with a mass (mass 2) of 3 kg. After the collision, the masses are moving at 5 m/s in the +x direction. What is change in total KE in the collision, in Joules? If negative, include a negative sign.
A block of mass m = 8.40 kg, moving on a horizontal frictionless surface with a speed 4.20 m/s, makes a perfectly elastic collision with a block of mass M at rest. After the collision, the 8.40 kg block recoils with a speed of 0.400 m/s. In the figure, the blocks are in contact for 0.200 s. What is the magnitude of the average force on the 8.40 kg block, while the two blocks are in contact?
3. A block of mass m = 6.2 kg, moving on a frictionless surface with a velocity of -6.5 m/s to the right, collides with a block of mass M at rest, as shown in the figure. After the collision, the 6.2-Kg block recoils with a velocity of f =0.70 m/s to the left. If the blocks are in contact for 0.30 s, what is the magnitude of the average force on the 6.2-kg block, while the two blocks are...
Question 1 10 pts 1) A mass of 4 kg is moving at some velocity and collides inelastically with a 7 kg moving in the-x direction at 10 m/s. After the collision, both masses are moving in the -x direction and the total kinetic energy of both masses is 68 Joules. What was the momentum of the 4 kg mass before collision in kg m/s? Include a negative sign if moving in the negativex direction.
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?
