Question

army can run ______then me​

Answer 1

Explanation:

given:

m=10 kg

u=2m/s

v=5m/s

according to work energy theorem ,work done by a force on a moving body is equal to the increase in kinetic energy according to work

thus,work done

=increase in k.e

=>1/2mv²-1/2mu²

=>1/2*m(v²-u²)

=>1/2*10*(5²-2²)

=>5*21

=>105 j

Answer 2

army can run fast then me
