A rod with a mass of 5 kg and a length of 9 meters is at rest in space with its long side pointing in the y direction. Two 12 kg masses of clay hit the rod at the same time and with the same speed of 18 m/s. One was traveling in the x direction before hitting and sticking to the top of the rod, and the other was traveling in the -x direction before hitting and sticking to the bottom of the rod. What will the magnitude of the angular velocity of the rod be in radians per second?

A satellite orbiting Earth at a velocity of 3700 m/s collides with a piece of space debris traveling at 6000 m/s. If the objects have the same mass and the space debris has a velocity after collision of 3700 m/s, what is the velocity of the satellite after the collision?

A joelshawon is a subatomic particle with a mass of 3.5 G and it is made out of a joelon (mass 1.5 g) and a shawon (mass 2g). A joelon going 7.9 x 10^6 m/s to the east collides with a shawon going 1.2 x 10^6 m/s to the north determine the speed and direction of the resulting joelshawon 

Three asteroids coated with cosmic slime are moving in the same plane when they collide and stick together. Initially, asteroid A has a mass of 2*107 kg and is moving to the right at a speed of 150 m/s, asteroid B has a mass of 3*107 kg and is moving at 50 m/s towards the lower left at an angle of 60 degrees with respect to asteroid A, while asteroid C has a mass of 5*107 kg and is moving with an unknown speed and angle. After the collision, the resulting single asteroid is moving toward the right at a speed of 50 m/s. Determine the speed and angle of asteroid C prior to the collision.

If one mass is much greater than the other, the larger mass stays essentially at rest while the smaller mass moves toward it. Suppose a 1.5×1013 kg comet is passing the orbit of Mars, heading straight for the 1.99×1030 kg sun at a speed of 4.5 ×104 m/s. What will its speed be when it crosses the orbit of Mercury? The orbit of Mars is 2.28×108 km, the orbit of Mercury is 5.79×107 km, and G = 6.67×10-11 N⋅m2/kg2.

An astronaut floating at rest in space has run out of fuel in her jetpack. She realizes that throwing tools from her toolkit in the opposite direction will help propel her back toward the space station. If the astronaut has a mass of 85 kg and she throws a hammer of mass 4.5 kg at a speed of 4 m/s, what will be the approximate resultant velocity that carries her back to the space station?

The carbon isotope 14C is used for carbon dating of archaeological artefacts. 14C decays to 14N by a process known as beta decay, in which the nucleus emits an electron (also known as a beta particle) and a subatomic particle called a neutrino. In one such decay, the electron and the neutrino are emitted in opposite directions to each other. The electron has a speed of 5 x 10 m/s and the neutrino has a momentum of 5 x 1024 kg m/s. n as What is the recoil speed of the resulting 14N nucleus? (Take the mass of the carbon-14 and nitrogen-14 nuclei to be 2.34 x 10 26 kg and the mass of the electron to be 9.11 x 1031 kg. If you were aware of such things and concerned, please ignore relativistic effects.)

Two rocks collide with each other in outer space, far from all other objects. Rock 1 with mass 5 kg has velocity {30,45,-20} m/s before the collision and {-10,50,-5} m/s after the collison. Rock 2 with mass 8 kg has velocity {-9,5,4} m/s before the collision. Calculate the final velocity of rock 2.

A mass of m1= 4 kg moving with a velocity of v1=(2 m/s)ˆi (positive x−direction) collides with another mass, m2 moving at v2= (−4 m/s)ˆi (negative x−direction).

A bomb is initially at rest and located at the origin of the coordinate system (0,0). The bomb explodes breaking up into three fragments of different masses. A camera registers the positions of the fragments after the explosion, as shown in the figure with (x,y) coordinates as follows: m1:(-6,5), m2:(5,0) and m3:(-3,-2), In the figure, the grid Y marks are separated by 1 m in each direction. Gravity and air resistance are negligible. m2 m3 What is the mass ratio of fragments 1 and 3? m,/m3 = 2/5 m1/m3 = 6/2 m1/m3 = 2/6
