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 bullet of mass 5X10^-3kg is fired from a 4kg gun with a speed of 320m/sec. With what speed does the gun recoil?
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?
See the attached file. The oscillation period is 1.25 seconds (just in case it's hard to read)
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
An 82 kg astronaut is space-walking outside the space capsule and is stationary when the tether line breaks. As a means of returning to the capsule, he throws his 3.1 kg wrench at a speed of 13 m/s away from the capsule. At what speed does the astronaut move toward the capsule?
A ball of mass m1 = 31.00 grams moving at 15.20 m/s collides head-on with a stationary ball of mass m2 = 116.00 grams. The collision is elastic. What is the velocity of the first ball immediately after the collision?
On a frictionless ice, a block whose mass is A= 6 kg is sliding toward +x with a velocity VA= 8 m/sec, when it collides in a non-elastic collision with a block of mass B= 4 kg moving at an unknown velocity VB. After collision the joined blocks move with momentum P= 84 i + 48 j where i and j are unit vectors. a. Find PB the or
N men, each with mass, m, stand on a railway flatcar of mass, M. They jump off one end of the flatcar with velocity u relative to the car. The car rolls in the opposite direction without friction. a) What is the final velocity of the flatcar if all the men jump at the same time? b) What is the final velocity of the flat
An instrument carrying projectile accidentally explodes at the top of its trajectory. The horizontal distance between the launch point and the point of explosion is L. The projectile breaks into pieces which fly apart horizonally. The larger piece has three times the mass of the smaller piece. To the surprise of the scientist in
Conservation of momentum in a capture collision of two masses initially moving in different directions.
Two joined known masses after collision are moving with given velocity. Before collision, the two move with non-parallel unknown velocities to be found.
