Hi there !!
Mass = 400 g = 0.4 kg
Velocity , v = 25 m/s
K.E = 1/2 ×mv²
= 1/2 ×0.4 × 25 ×25
= 125 Joules
Mass = 400 g = 0.4 kg
Velocity , v = 25 m/s
K.E = 1/2 ×mv²
= 1/2 ×0.4 × 25 ×25
= 125 Joules

Formula : K.E = 1/2 X mv²
Given :
m = 0.4 kg
v = 25 m/s
Solution:
= 1/2 X 0.4 X 25 X 25
= 125 J
Hope it helps.....................
