You throw a superball and a lump of putty of equal mass m at a wall. Both travel in the positive x-direction and hit the wall at speed v. The ball bounces back with the same speed, but the putty sticks to the wall. What is the change in momentum of the ball and the putty, respectively?

A baseball weighs approximately 142 g. A very good player can throw it at a speed of 145 km/h. a) What is the momentum of the ball? b) What force must a batter apply to stop the ball and return it if it contacts the bat for 0.4 s?

A ball weighing 10 kg is initially at rest, then suddenly explodes into 3 pieces. The picture shows the length and direction for each one of the three velocities. What were the length and direct of the ball before the explosion? Hint : use the momentum conservation principle on the y axis and x axis.

A certain radioactive (parent) nucleus transforms to a different (daughter) nucleus by emitting an electron and a neutrino. The parent was at rest at the origin of an xy coordinate system. The electron moves away from the origin with linear momentum (-7.8 × 10-22 kg m/s) î; the neutrino moves away from the origin with linear momentum (-2.8 × 10-23 kg m/s) j. What are (a) the magnitude and (b) angle (from the +x axis) of the linear momentum of the daughter nucleus? (c) If the daughter nucleus has a mass of 5.6 × 10-26 kg, what is its kinetic energy? (a) Number Units (b) Number i Units (c) Number i Units

A 40-ton rail car and an 80-ton rail car, initially at rest, are connected together with a giant but massless compressed spring between them. When released, the 40-ton car is pushed away at a speed of 3.0 m/s relative to the 80-ton car. What is the speed of the 40-ton car relative to the ground?

A fireworks rocket is moving at a speed of 30.465492001188 m/s. The rocket suddenly breaks into two pieces of equal mass, which fly off with velocities v₁ and v₂, as shown in the drawing. What is the magnitude of (a) v₁ and (b) v₂? 3₁ 30.0% 60.0

If a rainstorm drops 1 cm of rain over an area of 10 km² in the period of 1 hour, what is the momentum of the rain that falls in one second? Assume the terminal velocity of a raindrop is 10 m/s.

Need help with this physics question !

a) What is the total momentum of this two-astroid system? (Give answer in component form). Don’t forget to include appropriate units in your answers!

JD is playing with some clay (mass = 18-g).  He flings it across the room, where it lodges on the hood of a 259-g toy car that can freely roll back.  Once in motion, the clay/car combination moves with a speed of 0.78 m/s.  Determine the speed (in m/s) at which the clay was flung.
