In a certain system of absolute units the acceleration produced by gravity in a body falling freely is denoted by 4.9, the kinetic energy of a 20 kg shot moving with velocity 4 metres per second is denoted by 100, and its momentum by 10. Then find unit of length (in meter). (acceleration due to gravity = 9.8 m/s) %3D

please help me with this problem. Given: A ball of clay mass M/8 A larger mass as known as M is attached to a spring with spring constant k. A ball of clay mass "M/8" moves with speed "v" towards a larger mass M. As the a ball of clay hit and sticks on the a larger mass who was initially still. a) What would be the speed of the combination after the collision? b) How much did the spring compressed c) How long did it take for the spring to be compressed due to the collision?

Question  Particle A and particle B are held together with a compressed spring between them. When they are released, the spring pushes them apart, and they then fly off in opposite directions, free of the spring. The mass of A is 7.00 times the mass of B, and the energy stored in the spring was 88 J. Assume that the spring has negligible mass and that all its stored energy is transferred to the particles. Part (a) Once that transfer is complete, what is the kinetic energy of particle A?   Part (b) (b) Once that transfer is complete, what is the kinetic energy of particle B?

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

By what factor is the kinetic energy of an object will change if its momentum is increased in magnitude by a factor of 4? 16 4 8 2

calculate kinetic energy of mass 6kg. 192 joule Answer

One newly discovered light particle has a mass of m and property q. Suppose it moves within the vicinity of an extremely heavy (fixed in place) particle with a property Q and mass M. When the light particle is xi distance from the heavy particle, it is moving directly away from the heavy particle with a speed of vi. a) What is the lighter particle's speed when it is xf away from the heavy particle?
