Question

a 1.0kg ball is thrown into the air with initial velocity of 30 m/s, How much is the kinetic energy

Answer 1

• Mass=1kg
• Velocity=30m/s

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

$\\ \sf\longmapsto K.E=\dfrac{1}{2}1(30)^2$

$\\ \sf\longmapsto K.E=\dfrac{900}{2}$

$\\ \sf\longmapsto K.E=450J$
