A package of mass m is released from rest at a warehouse loading dock and slides down the 2.5-m-high, frictionless chute to a waiting truck. Unfortunately, the truck driver went on a break without having removed the previous package, of mass 2m, from the bottom of the chute. (Figure 1) Suppose the packages stick together.

A projectile has undergone an elastic one-dimensional collision with an initially stationary target, along an x axis. The figure below is a graph of position versus time for the projectile and target, before and after the collision. (Two line segments are parallel to the time axis.) Which is true about the masses of the projectile and target? 4 O the projectile's mass is greater O the target's mass is greater O the masses are equal

A0.014-kg bullet is fired intoa stationary block of wood of mass of 4.51 kg. The relative speed of the bullet with respect to the wood is zero after collision (The bullet becomes embedded in the block of wood). What is the speed of the bullet-plus-wood combination immediately after collision if the speed of the bullet before collision is 476 m/s? Express yourlanswer in two decimal places and with units of m/s.

Cart A has a mass 245 g. Cart B has a mass 406 g. The carts are on a frictionless track. Cart A is initially moving towards Cart B at a speed of 1.65 m/s and Cart B is initially moving towards Cart A at a speed 0.75 m/s. Determine the velocities of the cart after the collision. Determine the total kinetic energy of the carts after the collision.

A simple pendelum made of a pendelum bob of mass, m1=.0250 kg, and a string of length, l= .720m, is pulled back to an angle of theta = 35 degrees and then released from rest. At the bottom of the swing m1 and m2=.0200 kg collide and stick together. a. What is the speed of m1 immediately before it hits m2? b. What is the speed of m2 immediately after the collision? c. How high above the bottom of the swing do the two masses rise?

A mass m1= 3kg slides down slippery ramp, reaching a speed v=9 m/s at the bottom. After reaching the level ground m1 collides with mass m2= 4kg at bottom, sticking together in a perfectly inelastic collision. The combined mass then slides over a floor, finally coming to rest after travelling a horizontal distance x= 6m. a.) What was the height of the ramp, assuming that m1 started from rest? b.) How fast were the combined masses m1 and m2 moving after sticking together?

m₁ The figure shows two carts before a collision; cart m₁ is moving with velocity vo toward cart m₂ at rest. The carts slide without friction on the air track.

A 5 kg cart, cart A, moves with v=3m/s and collides with another 5 kg cart, cart B, head on at rest.  Neglecting air resistance and friction, do the following: Find the final velocity of the carts if the collision is perfectly inelastic. Find the linear momentum of each car before and after the collision if it is a perfectly inelastic collision. Find the kinetic energy before and after the collision if is perfectly inelastic. If the collision were elastic, what would be their final velocities? What would be the kinetic energy of each before and after the collision?
