Question

Something has a mass of 40 kg and a velocity of 1 m/s

Answer 1

• m=40kg
• v=1m/s

$\\ \sf\Rrightarrow K.E=\dfrac{1}{2}mv^2$

$\\ \sf\Rrightarrow K.E=\dfrac{1}{2}(40)(1)^2$

$\\ \sf\Rrightarrow K.E=20J$

Part 2:-

• m=80kg

$\\ \sf\Rrightarrow K.E=\dfrac{1}{2}(80)(1)^2$

$\\ \sf\Rrightarrow K.E=40J$

• Yes
