Question

If m= 28kg, v=15m/s. Find K.E​

Answer 1

Answer:

3150 kg-m²/s²

Explanation:

KE = 1/2mv²

m=28

v=15

KE= 1/2×28×15²

KE=14×225

KE=3150

Answer 2

$\boxed{\displaystyle\sf{K.E.=\frac{1}{2}mv^2}}$

Here,

• m = 28 kg

• v = 15 m/s

Applying the values to the equation,

$\displaystyle\sf{K.E.=\frac{1}{2}\times 28\times(15)^2$

$\implies\displaystyle\sf{K.E.=\frac{1}{2}\times 28\times225$

$\implies\displaystyle\sf{K.E.=\frac{6300}{2}$

$\implies\displaystyle\sf{K.E.=3150\:J$

$\boxed{\displaystyle\sf{K.E.=3150\:J}}$
