Convert planks constant in cgs system

in cgs system, plank's constant= h=6.626 x10⁻²⁶ erg s

Value of Plank's constant in SI system= 6.626 x10⁻³⁴ Js

now 1 Joule= 10⁷ ergs

so h= 6.626 x10⁻³⁴ Js (10⁷ ergs/1J)

h=6.626 x10⁻²⁷ erg s

What is the kinetic energy of a baseball moving at a speed of 40 m/s if the baseball has mass of 0.15 kg?

Kinetic Energy = 1/2 Mass (kg) * velocity squared (m/s)

KE = 1/2mV^2

KE = 1/2(0.15 kg)(40 m/s)^2

The answer is 120 joules.

0.5mv^2 > 0.5*0.15*40*40=120J
