MO-6 The Meteor Crater in Arizona is about 1,200m wide and 200m deep. It is believed to have been formed 20,000 years ago when a meteor with a mass of 5.0x10"kg moving at 7.2km/s collided and merged with the earth. If the earth had been at rest prior to the collision, what would the speed of the earth have been after this collision? The mass of the earth is 5.98x10"kg. 24

In this problem, an astronaut is landes on the 6.1×1021 kg asteroid traveling at 9830 m/s and detonates a nuclear bomb. The asteroid breaks into two pieces of equal mass. One piece will fly off at an angle of 30∘ and speed 9700 m/s. What will be the speed and angle of the second piece?
this is a multi step problem but I am just having trouble with this part of the problem. Here are the values that I correctly calculated: mass of particle 1=6 kg initial velocity for particle 1= 185i+138j final velocity for particle 1= -68.89i+-50.67j F21=-15.9e-t/96i+-100sin(2πt/96)j I am trying to find: What is the x displacement for particle 1? I think that I need to use Newtons second law to get an expression for acceleration, and then integrate but I am not getting the right answers.
