3. John is performing an experiment in a Uwindsor lab. In this lab, John has two toy car's of mass m1 and m2 connected together to form a car of mass m whose velocity is v. While traveling a force causes these car's to separate, with the heavier car being at rest as a result. If John notes the kinetic energy of the moving car is 28 mv 2 what is the mass of the moving car? А. 0.018m В. 5.1m C. 0.011m D. 0.028m Е. 0.11m

What is the mass of a large ship that has a momentum of 1.60 × 10^9 kg if the ship is moving at a speed of 48.0 km/h?

A particle with kinetic energy equal to 269 J has a momentum of magnitude 28.9 kg · m/s. Calculate the speed (in m/s) and the mass (in kg) of the particle. speed: ____ m/s mass: ____kg

A small spaceship whose mass is 2200 kg (including an astronaut) is drifting in outer space with negligible gravitational forces acting on it. If the astronaut turns on a 12 kW laser beam, what speed will the ship attain in 6.0 days because of the momentum carried away by the beam? Number i Units

An object has a kinetic energy of 312 J and a momentum of magnitude 29.3 kg · m/s. (a) Find the speed of the object. _____m/s (b) Find the mass of the object. ______kg

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

An object is traveling such that it has a momentum of magnitude 21.9 kg m/s and a kinetic energy of 300 J. Determine the following. (a) speed of the object in meters per second m/s (b) mass of the object in kilograms kg
