A 10 kg bomb is sliding across an ice rink southward at 6 m/s. It explodes....
A 10 kg bomb explodes into two parts. A 6 kg piece flies off with a speed of 6 m/s to the right. Find the speed and direction of the other piece if: 1 Phys 1201 Fall ’19 HW 5 Due Friday 10/25/19 by 5pm a) The bomb is stationary when it explodes. b) The bomb is moving to the right with a speed of 5 m/s when it explodes.
A bomb at rest at the origin of an xy-coordinate system explodes into three pieces. Just after the explosion, one piece, of mass 2 kg, moves with a velocity of 43 m/s in the negative x-direction, and a second piece, also of mass 2 kg, moves with a velocity of 30 m/s in the negative y-direction. The third piece has a mass of 7 kg. What is the initial momentum of the bomb before the explosion? What is the x-component...
A 400 kg bomb sitting at rest on a table explodes into three pieces. A 150 kg piece moves off to the East with a velocity of 150 m/s. A 100 kg piece moves off with a velocity of 200 m/s. What is the velocity of the third piece?
A hockey puck slides across an ice rink. Consider the origin to be at the center of the rink; the plane of the rink is the xz plane. At time t=0.0 s a hockey puck is observed to be at location <-6, 0,-5> m. At time t=0.2 sec, the puck is observed at location <6, 0, 2> m. a) What is the average velocity of the hockey puck during this time interval? b) What is the magnitude of the average...
Three ice skaters meet at the center of a rink and each stand at rest facing the center, within arm’s reach of the other two. On a signal, each skater pushes himself away from the other two across the frictionless ice. After the push, skater A with mass mA = 80.0 kg moves in the negative y-direction at 3.50 m/s and skater B with mass mB = 75.0 kg moves in the negative x-direction at 4.00 m/s. Find the x-...

An object with total mass mtotal = 16.2 kg is sitting at rest when it explodes into three pieces. One piece with mass m1 = 4.7 kg moves up and to the left at an angle of θ1 = 23° above the –x axis with a speed of v1 = 25.3 m/s. A second piece with mass m2 = 5.1 kg moves down and to the right, an angle of θ2 = 28° to the right of the -y axis...
A 4kg mess kit sliding on a frictionless horizontal surface, explodes into two 2 kg pieces. After the collision one part moves towards North with speed of 3 m/s and the other moves at 5 m/s in a direction 30° south of east. Determine the original velocity of the mess kit.
10.9 A radioactive nucleus (mass = 1.70*10-26 kg) is at rest. It suddenly decays (explodes) into three pieces. One piece has mass mi = 5.00*10-27 kg and is found to be moving along the +y axis with a speed of 6.00* 10 m/s. A second piece with mass m2 = 8.40*10-27 kg moves along the +x axis with a speed of 4.00* 10° m/s. Assuming the mass is held constant, find the velocity of the third and final piece that...
