Q. A proton (m=1.67x10-27 kg) is being accelerated along a straight line at 3.6*10^5 m/sec2 in a machine. If the proton has an initial speed of 2.4x10^7 m/sec.
what is the final velocity after travelling for 2 sec?
What is the increase in its kinetic energy?
A rattlesnake can strike with the acceleration equivalent to an increase in speed from 0 to 60 mi/h in 1/2 s. If the rattlesnake's head weighs 0.33 lb, what average power does the rattlesnake generate throughout its strike.
calculate the force of kinetic energy acting on Tom. calculate the distance from the edge of the table where Tom hits the floor.
