Answer:

so the kinetic energy is 20Nm

Explanation:

mass of the body=m=62kg

velocity of the body=v=0.8m/s

K.E.=?

AS WE KNOW THAT

K.E.=\frac{1}{2}mv²

putting values

K.E.=\frac{1}{2}}×62kg×(0.8m/s)²

K.E.=31kg×0.64m²/s²

K.E.=19.84Nm≈20Nm

i hope it will help you:)

You plan to take your hair blower to europe, where the electrical outlets put out 240 v instead of the 120 v seen in the united
Dmitrij [34]
P = U × I
I = P / U = 1600W / 120V = 13.4A
P = 240V × 13.4A = 3216W

If your hair blower isnt rated for 220- 230V(this is the voltage in EU) you are most likely going to burn it.
