Question

an object of mass 10 kg moving with a velocity of 36 km/hr after application of certain force its velocity changes to 54 km/hr find in K.E​

Answer 1

Answer:

Given : m=10 kg v=36 km/hr =36×

18

5

=10 m/s

Momentum of the body P=mv=10×10=100 kg.m/s

Answer 2

Answer:

v=36 km/hr

 v=36×185=10 m/s

     u=0

    t=10 sec

     v=u+at

    10=0+a(10)

    10=10a

    a=1 m/s2
