A 3.0 kg mess kit sliding on a frictionless surface explodes into two 1.5 kg parts, one moving at 1.6 m/s, due north, and the other at 6.7 m/s, 28° north of east. What is the original speed of the mess kit? Number i Units

A certain carbon monoxide molecule consists of a carbon atom of mass mc = 14 u and an oxygen atom of mass mo = 18 u that are separated by a distance of d = 122 pm, where "u" is an atomic unit of mass. a. Write a symbolic equation for the location of the center of mass of the carbon monoxide molecule relative to the position of the oxygen atom. This expression should be in terms of the masses of the atoms and the distance between them.  b. Calculate the numeric value for the center of mass of carbon monoxide in units of pm.

Three carts are moving on a frictionless horizontal track as shown in the figure.  The 4.00 kg cart is moving to the right with a speed of 7.0 m/s, the 10.0 kg cart is also moving to the right with a speed of 6.0 m/s while the 3.00 kg cart moves to the left with a speed of 7 m/s.  Find the final speed of the carts when they are all stuck together.   Hint:  The order at which the carts stick together does not matter.  Can you see why?

1. a. Starting from Newton's second law of motion, prove that impulse is equal to a change in momentum. b. A particle of mass m moves with a momentum of magnitude p. Show that the kinetic energy of the particle KE = i. =p²/2m

A 1470-kg car moving east at 17.0 m/s collides with a 1830-kg car moving south at 15.0 m/s, and the two cars connect together. How much kinetic energy was converted to another form during the collision? kJ

Problem 5: A 1.8 kg falcon catches a 0.65 kg dove from behind in midair. What is the speed of the pair of birds right after the catch if the falcon's initial speed was 28 m/s, the dove's initial speed was 7 m/s, and they were moving in the same direction?

At a carnival game, two balls are Identical in mass and radius, but one is made of steel and one is made of rubber. The game is to throw them at a bowling pin and try to knock it over. If the balls are thrown with the same speed and hit the same spot on the bowling pin, which Is more likely to knock it over? A. The steel ball B. Without knowing more information, this cannot be answered. C. Both are equally likely since they have the same momentum D. The rubber ball

A truck with a mass of 1600 kg and moving with a speed of 13.5 m/s rear-ends a 585 kg car stopped at an intersection. The collision is approximately elastic since the car is in neutral, the brakes are off, the metal bumpers line up well and do not get damaged. Find the speed of both vehicles after the collision in meters per second. V car 6.27 m/s V truck = 19.77 X m/s

a block with a mass of 0.5 kg is released from rest on a frictionless track at a distance 2.5m above the top of the table. it then collides elastically with an object having mass m2=1.0kg that is initially at rest on the table as shown in the figure. the table is h2=2.oo m . a)How far away from the bottom of the table do the objects land ? Hints : determine the velocities just after the collision . how high does object 1 travel back up the track. b) suppose the collision is inelastic , where does combined object land   please see attached image

A bullet of mass m = 0.025 kg is fired vertically towards a block of mass M= 1.57 kg. After the collision, the bullet exits the block with a speed of v/' = 50.3 m/s, and the block rises to a max height of 1.23 m. M mor a. Calculate the speed of the block after the collision.. b. Calculate the speed of the bullet before the collision. c. Calculate the change in kinetic energy during the collision. d. Is this collision elastic or inelastic? Explain.
