WebIn classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per … WebW 1 =300(16)cos(0)=4800 Joules; So the first part of the trip did 4800 joules. For the second part, we know that a 100N force moved the suitcase horizontally 8 meters, so the total amount of work done on the second portion of the trip is: W 2 =100(8)cos(0)=800 Joules; Combining the two values from each portion of the trip yields:
WebIn order to answer the question the first thing to do is divide the result by watts (remember that 1 watt is 1 joule per second): 9 x 10 16 J / 100 W = 9 x 10 14 seconds That's a lot of seconds, but how long is that in years? A year (365.25 days) is 31,557,600 seconds, so: 9 x 10 14 seconds / 31,557,600 seconds = 28,519,279 years WebDec 6, 2024 · The first step is to set the equations for gravitational potential energy and work equal to each other and solve for force. W=PE=Fd=mgh \implies F=\frac {mgh} {d} W = PE = F d = mgh F = dmgh. The second and final step is to plug the values from the problem into the equation for force. Remember to use meters, not centimeters, for all distances.
