Blocks A and B in Figure 13 have a mass of 80 kg and 8 kg respectively. With the method of your choice (kinetics/kinematics or work-energy), determine the distance covered by block A to pass from its rest position at a speed of 0.5m/s. Check your calculations with the pulse and pulse method. momentum.

An older-model car accelerates from 0 to speed vin 15 s. A newer, more powerful sports car of the same mass accelerates from 0 to 3v in the same time period. Assuming the energy coming from the engine appears only as kinetic energy of the cars, compare the power of the two cars.

A particle initially has a speed of 0.37c. (Enter your answers in terms of c. Round your answers to at least three decimal places.) (a) At what speed does its momentum increase by 1%? 0.41 X с (b) At what speed does its momentum increase by 10%? (c) At what speed does its momentum increase by 100%?

[Special Relativity] Two hypothetical X particles, each with mass m, collide head-on with the same magnitude of momentum, in the lab frame. The collision produces two new Y particles, each with mass 2m. What is the minimum kinetic energy, in the lab frame, of each X particle to achieve this process? O a. √2m O b. √3m O c. m O d. 2m.

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 32.90 milligrams flies by your head at 4.53 km/h. magnitude of the momentum: A 30.70 km boy walks at 4.27 km/h. magnitude of the momentum: A car with mass 997 kg is moving at a speed of 40.1 km/h. magnitude of the momentum: Based on the previous results, which scenario likely describes an object possessing 1 kg-m/s? a mosquito flying through a swamp a cat walking down a sidewalk a beetle walking across a jungle floor a tiger running after prey an elephant running across a field kg-m/s kg-m/s kg-m/s

Show that the kinetic energy of a particle of mass m is related to the momentum p of that particleby, ? =p^2/2m. (Hint: plug mv in for p and simplify!)

My last step was F=.57mg/Cos(-15.1)+(0.57 Sin (15.1) Outcome of 0.6977mg I think I found the The condition for moving a block but I don’t know what to do next.I’m confused

a physics student start sailing away in a boat at 5.0 m/s as shown in the diagram. When they are 50.0 m from the shore, Mr Berthiaume spots them, and launches a copy of the exam towards the boat so they will have no choice but to complete it.  Using every quantum of strength in his body, he throws the exam with a speed of 40.0 m/s, while summoning physics to remove air resistance for the moment.  The exam lands on the boat after the boat has moved another 50.0 m.   (a) At what angle above the horizontal must Mr Berthiaume throw the exam so it lands on the boat? (b) How high is the cliff? (c) With what velocity does the exam hit the boat?

A particle of mass m moves with a momentum of magnitude p. Express p in terms of KE.

A particle is moving at  0.75c relative to a lab on Earth. By what percentage is the Newtonian expression for its momentum in error? (The percentage error is the difference between the erroneous and correct values, divided by the correct one).
