    Elastic Collision and Kinetic Energy Transfer

    A 0.343 kg croquet ball makes an elastic head-on collision with a second ball initially at rest. The second ball moves off with one half the original speed of the first ball. 1) What is the mass of the second ball? And 2) what fraction of the original kinetic energy gets transferred to the second ball?

    Conservation of Linear Momentum,.,

    Hi. Can someone please show me how to do the following problem? "A 5620 kg open railroad car coasts along with a constant speed of 8.66 m/s on a level track. Snow begins to fall vertically and fills the car at a rate of 3.50 kg per minute. Ignoring friction with the tracks, what is the speed of the car after 86.4 minutes?"

    Linear Momentum

    "Find the speed at which Superman (mass = 89.0 g) must fly head-on into a train (mass = 16405 kg) traveling at 75.0 km/hr to stop it."

    Linear momentum: Find speed of a golf ball just after impact

    High speed stroboscopic photographs show that the head of a 184 g golf club is traveling at 52.9 m/s just before it strikes a 45.1 g golf ball at rest on a tee. After the collision, the club head travels (in the same direction) at 42.2 m/s. Find the speed of the golf ball just after impact. Ignore the mass of the club handle.

    Linear momentum

    "A 122 kg astronaut (including space suit) acquires a speed of 2.50 m/s by pushing off with his legs from a 1900 kg space capsule. What is the change in speed of the capsule?"

    Momentum and velocity

    An object of mass 2 kg travelling in a straight line with a velocity of 20m/sec collides with, and strikes to, a stationary object of mass 3 kg. They both move off together in the same straight line with a velocity of v m/sec. If no external forces are acting calculate a. the total momentum just before the impact b. the tot

    Mechanics force, mass and momentum of an object

    Q. An object sitting on a smooth surface is given an impulse (force) to start from rest and reached a veloctiy of 5m/sec in 2 seconds. 1. What is the mass of the object if the applied force was 20 N 2. What is the change in momentum 3. At the time given above the object is travelling towards the northwest with an angle

    Impulse and Momentum: Small steel ball moving with speed v0

    A small steel ball moving with speed v0 in the positive x-direction makes a perfectly elastic noncentral collision with an identical ball originally at rest. After impact, the first ball moves with speed v1 in the first quadrant at an angle theta1 with the x-axis, and the second moves with speed v2 in the fourth quadrant at an

    Conservation of Momentum

    If a metal ball strikes a pendulum and sticks to it. It will have a relationship for conservation of momentum of m*v = (m + M) *V (m and v are the mass and initial velocity of the projectile, M is the mass of the pendulum with no initial velocity and big V is the combined velocity of the pendulum and projectile). The conse

    A man of 60 kg mass is stuck on a sheet of ice 10m from solid land. The coefficient of friction between the man and ice is 0.03. He has a 5 kg rock which he can throw with a speed of 12 m/s. a) Can he reach solid land by throwing the rock? b) If so, how long will it take him?

    Conservation of momentum in a collision situation

    In a football game, a receiver is standing still, having just caught a pass. Before he can move, a tackler, running at a velocity of +4.5 m/s, grabs him. The tackler holds onto the receiver, and the two move off together with a velocity of +2.6 m/s. The mass of the tackler is 115 kg. Assuming that momentum is conserved, find

    Object Velocities Applied Mechanics

    A 1 kg object is dropped from the horizontal while attached to a string 80 cm long, tied at the same height as the object. When the string is vertical after the object is dropped, the object strikes a 2 kg block on a frictionless horizontal surface. The impact is 100% elastic. What will be the velocities of both objects

    Working with momentum conservation.
