It is generally a good idea to gain an understanding of the size of units. Consider each object and calculate the magnitude of their momentum in SI units. A ladybug with mass 28.50 milligrams flies by your head at 3.75 km/h. magnitude of the momentum: kg-m/s A 37.90 km boy walks at 4.05 km/h. magnitude of the momentum: kg-m/s A car with mass 841 kg is moving at a speed of 41.3 km/h. magnitude of the momentum: kg-m/s
1. Calculate the magnitude of the linear momentum for the following cases: (Serway & Vuille, 2012) A. A proton with mass equal to 1.67x10-27 kg, moving with a velocity of 5.00x10⁰ m/s; B. A 15.0 g bullet is moving with a speed of 300. m/s; C. A 75.0 kg sprinter running with a velocity of 10.0 m/s; and D. The Earth (m=5.98x 1024 kg) moving at an orbital speed equal to 2.98x10 m/s.
The following question concerns a collision in outer space, far enough from any planets so that the external forces can be considered as negligible. An unmanned spacecraft, having mass 1,500,000 kg and speed 25,000 km/hr collides with a small meteor, having mass 3,000 kg and speed 2,100 km/hr, in the Kuiper belt. a. Prior to the collision, what are the total kinetic energy and total momentum? b. Assuming a head-on collision, in which the meteor becomes lodged into the spacecraft’s body and the two objects move off together, what are the total kinetic energy and momentum after the collision? c. If instead of getting lodged into the spacecraft, the meteor bounced off, would the change in the space craft’s momentum be larger or smaller, or is there not enough information to tell? Explain.
In the game of pool, all the balls have the same mass (0.17 kg). Look at the figure carefully. The white cue ball hits the black ball which was initially at rest on the table. The image below shows what happens to each ball. The black ball has a speed of 1.5 m/s after the collision. What is the speed of the white cue ball after the collision? 3.0 m/s a) 1.8 m/s b) 2.6 m/s c) 4.3 m/s d) 5.2 m/s e) 1.5 m/s 30.0° 60.0° 1.5 m/s
A child runs at 3.0 m/s and jumps onto a sled, initially at rest. If the child's mass is 40 kg, and the sled's mass is 20 kg, what is the speed the child and sled slide off together after the collision? O2.0 m/s O 0.5 m/s O 3.0 m/s O 1.0 m/s
You and another astronaut are in space. You throw a tool to them that has a mass of 17kg. Your mass is 87kg and the other astronaut's mass is 91kg. Initially you and the other astronaut are at rest. You threw the tool at a speed of 7m/s. What is the velocity of the astronaut after they catch the tool?

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.
A man walks up to you and hands you an energy drink with mass 0.4 kg. You decide energy drinks aren't for you and throw it on the ground. At the moment the energy drink leaves your hand, it is moving downwards with a speed of 7 m/s and is 1 meter above the ground. Calculate the speed of the energy drink in m/s just before it impacts the ground. As before, assume g = 10 m/s^2. You may neglect air friction. Round your answer to one decimal place.

Your mass is 63.2 kg, and the sled s mass is 21.7 kg. You start at rest, and then you jump off the sled, after which the empty sled is traveling at a speed of 4.27 m/s. What will be your speed on the ice after jumping off? 1.47 m/s 0.88 m/s 2.06 m/s 1.77 m/s
A mass m1= 3kg slides down slippery ramp, reaching a speed v=9 m/s at the bottom. After reaching the level ground m1 collides with mass m2= 4kg at bottom, sticking together in a perfectly inelastic collision. The combined mass then slides over a floor, finally coming to rest after travelling a horizontal distance x= 6m. a.) What was the height of the ramp, assuming that m1 started from rest? b.) How fast were the combined masses m1 and m2 moving after sticking together?
