Calculate the speed at which a 0.723-kg object has the same momentum as a 1.30-kg object that is moving a: 0.515 c. b: 0.712 c c: 0.734 c d: 0.981 c e: 0.592 c What is the kinetic energy of a 200 g bullet travelling at a velocity of 400 ...
If the mass m and muzzle velocity v of a bullet are known, its kinetic energy and momentum can be determined from the relationships Ek= (1/2)mv2and momentum **p** = m**v**. This information in turn...
Power is a rate that relates energy and time together, as it expresses the amount of energy spent during a certain interval of time. So the higher the value of power, the more energy is spent during a process or an activity. There ...
Describing these two kinds of motion are treated as separate physics problems; that is, when calculating the distance the ball travels through the air based on things like its initial launch angle and the speed with which it leaves the bat, you can ignore its rotation, and when calculating it...
