Question

19. A stone having mass of
1000 gm is falling from a
height. How much kinetic
energy does it have at the
moment when its velocity is 2
m/s? *​

Answer 1

Answer:

mass =250gm =250/1000 =1/4 kg

velocity =2m/s

K.E. =1/2mv²

=) 1/2*1/4*2*2

=) 1/2joules

Explanation:

hope it helps

Answer 2

Answer:

m=1000gm=1kg

v=2m/s

KE= 1/2×mv^2

KE= 1/2×1×2×2

KE=2 joule..
