mass =250gm =250/1000 =1/4 kg
velocity =2m/s
K.E. =1/2mv²
=) 1/2*1/4*2*2
=) 1/2joules
velocity =2m/s
K.E. =1/2mv²
=) 1/2*1/4*2*2
=) 1/2joules

Mass=250gm we have to change in kilometers.
So, 0.25km
Velocity =2 m/s
1/2×m×v2
=1/2×0.25×2×2
=0.50J
So, 0.25km
Velocity =2 m/s
1/2×m×v2
=1/2×0.25×2×2
=0.50J
