What is the kinetic energy of an object that has a mass of 20 kilograms and a speed of?

This object of yours could be a cart speeding at 2.8m/s





._鈻撯枔._鈫扸 = 2.8m/s

m = 20kgs





The formula is





KE = 陆mV 虏


......= 陆(20)(2.8) 虏


......= 10 (7.84)


KE = 78.4kg-m or 78.4JoulesWhat is the kinetic energy of an object that has a mass of 20 kilograms and a speed of?
What's the speed? I can't answer it if you don't put the speed of the object. But I can say that KE=1/2mv^2





Sorry bout my delay. If you haven't figured it out yet, the answer is KE=1/2(20)(2.8)^2


Make sure you abide by the order of operations. Square the 2.8 first, then multiply the rest out.





KE= 78.4 JWhat is the kinetic energy of an object that has a mass of 20 kilograms and a speed of?
k energy = 1/2mass X speed^2





put the numbers in, so would be


k= 10 X ____^2





i think!
you can find out by make it move and see how fast it stops use weights to do it but i would say around 7
wtf kind of question is that?





Ke = 0.5mv2





you have 2 unknowns and 1 equation, your question is incoherent...
7
KE = (1/2)*m*v^2
