An object of mass m moves to the right with a speed v. It collides head-on with an object of mass 3m moving with speed v/3 in the opposite direction. If the two objects stick together, what is the speed of the combined object, of mass 4m, after the collision?

A puck of mass mA that is moving along the +x axis with speed va collides with another puck of mass mB = 2mA. The collision is not head-on, so that after they collide, mB is located at 45◦ south of east, while mA collides head-on elastically with a stationary puck of mass mC = 3mA. If, after the second collision, the final velocity of mC is 0.450 [m/s], 25◦ north of east, what is the initial speed va?

A joelshawon is a subatomic particle with a mass of 15.7g and it is made of a Joelon (mass 7.6g) and a Shawon (mass 8.1g). A joelon going 3.6 x 10^6 m/s to the east collides with a shawon going 1.1 x 10^6 m/s to the North. Determine the speed and direction of the resulting joelshawon

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). The masses collide and stick together, moving off with a velocity of v= (−2 m/s)ˆi. What is m2? A)m2= 4 kg B)m2= 8 kg C)m2= 12 kg D)m2= 16 kg

Two masses, m, and m, move on the xy plane towards each other as shown in the figure. The first mass m,=1.1kg is moving with a speed v,=6.7m/s while m,-4.3kg is moving with a speed v,=10.6m/s . As a result of the collision m, comes to rest. What is the final speed of m,? Express your answer using two decimal places. Before the collision

In an Atwoods Machine lab with m1 = 0.1 and m2 = 0.13 observed acceleration is 1.20 m/s^2. Compare the value with the a(theoretical).   During the momentum collision lab a 2.5kg mass moving with 2m/s hits a stationary 5kg mass. After the collision 2.5kg bounces back with 0.5m/s and 5kg mass moves with 1.2 m/s. Calculate Pi and Pf and compare using percent error. Does this experiment show conservation of momentum?

Betty (mass 47 kg) stands on an ice rink as Bubbles (her hyperactive puppy, mass 6.9 kg)) runs towards her and leaps into her arms. If they move off together with a speed of 0.77 m/s, how fast (in m/s) was Bubbles moving when Betty caught her?

An object, with mass 88 kg and speed 18 m/s relative to an observer, explodes into two pieces, one 4 times as massive as the other; the explosion takes place in deep space. The less massive piece stops relative to the observer. How much kinetic energy is added to the system during the explosion, as measured in the observer's reference frame?

You are sitting in a sled, at rest on a pond covered with nice, thick, frictionless ice. Your own mass is 82.3 kg, and the mass of the sled when empty is 20.8 kg. From shore, someone throws a baseball of mass 0.122 kg to you, and you catch it; the horizontal component of the ball s velocity is 29.4 m/s. What will be the sled s (and your) speed with respect to the surface of the pond after you catch the ball? 17.1 cm/s 2.08 cm/s 3.47 cm/s 4.35 cm/s

An unstable nucleus of mass 1.7 ✕ 10−26 kg, initially at rest at the origin of a coordinate system, disintegrates into three particles. One particle, having a mass of m1 = 1.8 ✕ 10−27 kg,moves in the positive y-direction with speed v1 = 5.4 ✕ 106 m/s. Another particle, of mass m2 = 9.0 ✕ 10−27 kg, moves in the positive x-direction with speed v2 = 3.2 ✕ 106 m/s. Find the magnitude and direction of the velocity of the third particle.
